Power over Ethernet for power management silicon components

(Trackback: http://www.best-laptop-battery.co.uk/blog )

Ethernet “refers to the use of a variety of standard IEEE802.3 LAN (LAN) system. Ethernet is the application of a workplace agreement, for example, by high-speed data cable to the desktop PC and connect the central file server. Data Terminal , wireless access points, network cameras and phones connected to the Ethernet ports of any of the equipment has to have its own power, which can be battery power can also be a separate AC outlet. and a more attractive idea is can at the same time, power and data to any connected to the Ethernet equipment. If the transmission is designed to make use of existing Ethernet cables, can be 100% backwards compatibility, it is better

This is included in the IEEE802.3af Power over Ethernet (PoE) standard can be done. The new standard in 2003, 6 menstrual IEEE approval for Ethernet transmit and receive signal power.

The advantages of PoE are:

● applications only need a set of wires, cables has become easier, lower cost.
● save AC adapter socket, and after the work environment more safe, clean, cost be reduced accordingly.
● Applications can be easily moved from one another.
● When the AC main line power failure, an uninterruptible power supply to ensure that the application of electricity required.
● remote monitoring and control can be connected to the Ethernet equipment.

Power over Ethernet which has allowed rapid progress as a new technology, which fundamentally changed the type of equipment, low-power power supply. There are more power-driven equipment through Ethernet. Today, there are two main types of PoE power devices become a leading force in sales growth, they are: wireless LAN access points and VoIP phones. The former compound growth rate of 38%, and in 2007 reached 15 million (Source: iSuppli), and support enterprise-class network which in 2007 is expected to be reached three million. Of power in turn drives the demand requirements of the existing Ethernet switch can support PoE. This can be shown in the “middle style” program to achieve. Is expected by 2007, the number of such equipment will grow to 800 million, growth rate of 68%.

In this case, the original Ethernet switch through the “middle style” Power-over-Ethernet hub to twisted-pair LAN cable into the power, the realization of PoE. Ethernet switch will be combined with the new “half-way” approach for the adoption of high-speed data cable to connect the power device (PD) power. Of these electrical equipment can be a network of cameras, VoIP phones, wireless LAN access points and other equipment. Uninterruptible power supply (UPS) to the main power supply to provide backup electrical power.

Power management devices used in Ethernet switches and Power over Ethernet “-style half-way” hub conversion voltage and current, as well as electrical equipment in the DC-DC converters.

Ethernet switch in the power management device

Up-to-date through the Ethernet switch 24 or 48 independent ports provide PoE for the electrical equipment connected to the following non-PoE-compatible system. Each device has its own power 48V power supply, each of PD up to 15.4W, respectively, by the Ethernet switch management.

IEEE802.3af PoE standard allows the maximum power consumption of equipment in the 13W or so – taking into account the long-distance transmission cables have a certain degree of power loss, Ethernet switch to provide power 15.4W. End-use electrical equipment when the 48V power supply voltage range 36 ~ 57V, the voltage reaches the maximum allowed twice about switching voltage (such as peak signal switches, etc.), require the use of a power switch for 100V rated VDS discrete MOSFET.

PoE controller generally refers to “hot swap” controller. The function of this type of IC are:

● Separation of independent control of the four PoE ports.
● Detection of electrical equipment and effective connections.
● Monitoring of the MOSFET under steady-state current (through the low-ohm resistor sensor).
● PD when connected to the port on the influx of current and thermal control MOSFET.
● When the PD disconnect, a low-current disconnect function.

In common mode, once the power supply port, PD port by-pass capacitor voltage power supply, external MOSFET power scattered is very small. This shows that a small MOSFET will be able to meet this need. However, IEEE802.3af there are a number of other needs, such as the surge current is turned on and electrical equipment are not compatible with the issue of ports, which need a lot of energy in the instantaneous spread of the MOSFET. That is why the use of discrete MOSFET integrated solutions rather than the causes.

Ethernet switch MOSFET also called for the closure of the leakage when the volume is lower. Asking for a port IEEE802.3af absolute maximum amount of leakage can not exceed 12 basis, this figure including the MOSFET and other circuit protection of the leakage path of leakage current. Philips Semiconductors of the MOSFET design to meet this requirement.

Battery has become the key mobile office applications

At present, the mobile office concept has already become a reality. In order to meet the needs of mobile and mainstream manufacturers are introducing more powerful, more stable system of ultra-thin notebook PCs, and notebooks accounted for 10% of the overall price -15% of the battery performance, but also more and more manufacturers concern.

In fact, the value of the battery often underestimated, and even a lot of people in the time to buy laptop battery had simply ignored the problem completely. However, from the perspective of mobile office, but in the practical application of the battery often play an extremely important role. According to the relevant person in charge of NEC, at present, a common ultra-thin notebook battery time between 2-3 hours, a good brand can be achieved for about four hours. NEC S820 will be able to provide electricity five hours time, and the S820 weighs only 1.36Kg, the fuselage is only 16.6 millimeters thick. At the same time, with a backup battery, S820’s life will be a staggering 11.8 hours.

Looking at the market most of ultra-thin notebook computers, cell expansion have not been able to achieve “full portable,” and after loading so that the lower part of the formation of convex body, that affects the body and reduces the appearance of the portable , and for users This is a fly in the ointment. NEC was the first to put forward a “no protruding objects” Smoothing the concept of battery design, the S820 is designed to extend the battery very thin flat-shaped, S820 Ultra Low Voltage CPU, the motherboard to use a large number of high-quality low-power components , as well as through high-quality CPU power management features with the control, reduce unnecessary power consumption, so as to achieve a minimum energy. Smoothing these unique battery design that is available once the evaluation was very high, is considered the appearance of laptop battery “revolutionary” design.

There analysis of the industry, with the ever-increasing Internet bandwidth and the increasing popularity of wireless networks, mobile notebook PC will become the most widely used, which includes not only people existing “mobile office” concept, entertainment, communications, and other day-to-day non-business mobile applications will also be popular, as the energy source of laptop battery is bound to become the top priority. Experts predict that in the near future, there will be more vendors to join the main energy-saving technologies and notebook battery R & D ranks, with new material made of small size, high-capacity, long time, a high end portable battery products laptop battery will become the main trend of the application.

Fuel cell vehicles 4 years after the start, the recent launch first hybrid vehicle

In 2003, China’s energy consumption level has been flat and Japan, will surpass Japan this year, after the United States to become the second largest energy consumption power. China’s oil consumption in total energy consumption accounted for about 25%, which accounted for gasoline consumption in the car around 70%. According to projections, by 2020 China will have a car full of vehicle ownership is the amount of 5 times the energy consumption can only sustain the current 2-fold, research alternative energy sources is urgent car.

As a large city, how to develop the city’s environmental protection and energy saving cars have become a major issue. According to the officers revealed that the city will soon launch a hybrid car, is expected to launch long-term light-fuel vehicles. 2008-2010, the city of light fuel vehicles is expected to start.

At present, the city of CNG (compressed natural gas), about 150 buses are being used, LPG (liquefied petroleum gas) are more than 10,000 taxi cars. According to a three-year environmental protection plan, the city of CNG buses in future will be about 3000. — 863 research projects and go beyond the fuel cell vehicle on the 2nd through the Ministry of Science and Technology in a recent inspection, which will also further developed a variety of models, is expected to extend the study to the next five-year plan.

According to international forecasts, from 2010 to 2015, the world will be a major fuel cell vehicle production, vehicle production will be a new revolution. China’s fuel cell vehicles is expected in 2008 Olympics and the World Expo 2010 will take place during the model run.

Electric Vehicles and Environmental Protection

(Trackback: http://www.best-laptop-battery.co.uk/blog )

Large-scale use of motor vehicles is one of the main causes of air pollution, especially in large cities. Control of air pollution in a number of recommendations, it was suggested that: “the electric car of the 21st century — a clean means of transport”, the theme of the concept of people in environmental protection today is very appealing. However, electric vehicles can really solve the problem of pollution from motor vehicles? The development of environment-friendly car electric vehicle only a way out right? For answers to these questions, we are still divergent views. Why electric vehicles become a hot spot? Advocates believe that electric vehicles, electric vehicles has the following advantages:

First of all, electric vehicles are considered “zero pollution” car, it can effectively improve the urban air quality, reduce noise pollution. Because of pollution caused by motor vehicles include harmful exhaust, noise and dust raised, which is the most harmful emissions. According to the analysis of automobile exhaust gas composition in a variety of more than 1000 kinds, about which the greatest harm on the human body is carbon monoxide, hydrocarbons and nitrogen oxides and so on. These harmful substances can lead to respiratory diseases, physiological dysfunction, and even lead to cancer. The use of electric vehicles, no matter what kind of battery, resulting in minimal emissions, equivalent to only an ordinary internal combustion engines of motor vehicles 2% ~ 8%. At the same time, the work of motor noise is very small, only half of an ordinary engine.

Second, electric vehicles powered by electricity, a variety of energy sources, we can make use of coal, petroleum, natural gas and other fossil fuels resources, can also arise from hydro, wind, tidal, geothermal and nuclear energy, the relative scarcity of savings oil resources. Geological experts estimate that the current exploitation rate, the world’s proven oil reserves will be depleted in several decades. In China, the oil was the shortage of mineral resources as the first. Thus, diversification of energy policies, reduce dependence on oil and consumption, has become the consensus of many countries. It is estimated that motor vehicle fuel may be the world’s oil consumption accounted for 40% of the total. If we can significantly reduce the car the “big oil” the amount of fuel consumption, it would be exciting! From this perspective, the electric car is indeed a very good choice.

Third, some experts believe that the use of electric vehicles, energy efficiency than internal combustion engine vehicle high. For example, electric vehicles in the traffic jams do not need to idle when the engine running, not to energy; braking when the motor generator can play a role, that is able to translate into vehicle kinetic energy into electrical energy storage battery. In addition, studies have shown that after a rough equivalent of crude oil refining to power generation, and then charge into the batteries, drive motor drive energy efficiency of motor vehicles, refined into gasoline than after transport, refueling, and then by engine-driven car high two percentage points. It is due to the above-mentioned advantages of electric vehicles became the excitement of the automotive industry and the world’s major manufacturers of the key technologies of the future competition. However, critics of electric vehicles has never been stopped, and efforts to have the same convincing.

Critics from the three aspects of electric vehicles to be negative. First, the electric vehicle is a “zero emissions” and not really down pollution, and pollution of the environment may be more; At the same time, some experts do not agree with electric vehicles, energy-saving point of view. They think that electric vehicles and gasoline pollution cars should be driven from the driving energy to the whole process of comparison. At present, coal-fueled power plant occupies a large proportion, caused by electric cars to increase power consumption will lead to increased power plant emissions; burning of coal will produce a large number of sulfur oxides, which is a major factor in acid rain, and the pollution in the gasoline car is almost non-existent. The method of calculating the same conclusion is that electric vehicles produce pollution of nitrogen oxide than gasoline cars high a few percentage points, from low carbon dioxide emissions than petrol vehicles of approximately 20%. Therefore, the electric vehicle does not really achieve environmental goals, but the car exhaust pipe emissions of pollution into the chimney of a power plant only.

Second, the batteries of electric vehicles for the use of lead-acid batteries, manufacturing, use of these batteries will have serious environmental pollution. Manufacturing lead-acid batteries will be mining, refining large amounts of toxic lead, which is bound to mines and factories are polluting the surrounding environment, At the same time, the battery will be used to create a large number of heavy metals such as cadmium, nickel, etc., these heavy metal wastes is a serious If these toxic wastes infiltrate aquifers would result in serious water pollution. If large-scale use of lead-acid batteries, but also a large amount of lead compounds, lead compounds may even be the pollution of air pollution than the present even more serious. Therefore, unless the sound of electric vehicles to find the battery, or the degree of pollution may be higher than gasoline cars.

Third, we should address the use of electric vehicles, energy efficiency point of view, some energy experts also questioned. They believe that electric vehicles from the entire process of energy utilization, the efficiency of coal-fired electricity is about 34%, 94% transmission efficiency, battery efficiency of 90%, motor-driven efficiency of motor sport for 80% of the total efficiency of only 23% higher than the efficiency of gasoline engines is even lower.

Based on the above analysis, some foreign experts sharply pointed out that electric vehicles are not really out of environmental considerations, but also we can not solve environmental problems, it was the reason why the rapid development of a very important reason is that car manufacturers in order to achieve a growing the more stringent emissions standards and regulations, can only adopt the expedient development of electric vehicles. In fact, the competition is to develop electric vehicles, to a large extent inhibited oil alternative fuels the development of environmentally friendly vehicles. The outcome of this dispute is not important, its significance lies in the deepening of the automotive research and other environmental issues, draw attention to the development of other environment-friendly vehicle, these vehicles include: solar cars, hydrogen fuel cars, compressed natural gas vehicles and hybrid electric vehicle and so on.

Spinach will be the future of battery

In the cartoon “Popeye”, the spinach is a food is full of energy. Recently, scientists found a vegetable extract from the real energy. In this way, scientists invented a so-called “spinach cells”, such as long battery life for more than three weeks, can be applied to mobile phones, laptops and other mobile devices.

Scientists use the principle of the photosynthesis of green plants. Spinach selected mainly because of its high chlorophyll content, prices, and the four seasons can be used. Although photosynthesis can transform sunlight into energy, but now in the early stages of the experiment, this battery can not produce electricity, only the use of solar energy to extend battery life.

Spinach scientists first dissolved in the centrifuge, the protein extracted from them; and then again a peptide detergent into the gap in the protein; then inject the mixture of plastic, gold, indium tin oxide, as well as transparent semiconductor material through a gap between the layers, made of a chip. The chip is not only durable and easy to repair: When the battery to stop working, it is easy to add protein to the inside.

So far, the chip is only developed the solution that a layer of spinach, it can also have a weak point of the current. Scientists plan to increase the level of the other to produce more energy. At present, the study is still in the early stages, scientists also can not predict within ten years for commercial applications.

This is the first time extracted from the photosynthesis of current such as the basic material. This finding indicates that there is indeed such a way that can be generated by molecular biological combine directly applied to the circuit.

Microbial fuel cell

(Trackback: http://www.best-laptop-battery.co.uk/blog )

Since the industrial revolution, has been plagued sewage treatment in developed and developing countries a major problem, because it expensive, is only of inputs, not outputs of the industry. And new microbial fuel cell can not only purify the water, but also for power generation, the emergence of its sewage treatment is expected to become a profitable industry. Although still in the continuous improvement of the product has not yet put into commercial production, but we have every reason to believe it has broad prospects for development.

Recently, by the United States Pennsylvania State University scientists, led by Logan, a research and development team announced that they have developed a new type of microbial fuel cell can be of untreated sewage into clean water and power.

Microbial fuel cell (MicrobiologicalFuelCells) there is not just a technology. As early as 1910, the British botanist Mark – the first bit of bacteria found in the culture medium to produce current, therefore, he made use of platinum electrodes, put it into E. coli and general yeast culture medium, the successful production of a the world’s first microbial fuel cell; in 1984, the United States to create a space for use in microbial fuel cell, which fuel for the astronauts of the urine and live bacteria, but it’s a very low discharge rate; In recent years, the use of Microbial generation of technology breakthroughs have emerged more, Pennsylvania State University environmental engineering professor Bruce – Logan is a new microbial fuel cell development team, he said, “the traditional is the use of hydrogen fuel cell power generation, but no one try to use organic-rich water to generate electricity. ”

A major innovation: a single slot design

Logan designed the battery and hydrogen fuel cell device to be somewhat similar, is a sealed cylindrical glass tank of resin, looks like a soda bottle. And hydrogen fuel cells, however different, the microbial fuel cell is a single reaction tank, containing eight graphite anode rod, and they stick around a cathode, confined to the middle slot between proton exchange membrane. Confined to the external tank of the closed circuit composed of copper, used for electronic flow path. When water was injected into reaction tank, the bacterial enzyme to break down organic matter in sewage, in the process of releasing electrons and protons. Among them, the electronic flow of the anode, and protons through the proton exchange membrane inside the flow of anode, where oxygen and air as well as the electronic generation of clean water combined. Thus completion of the sewage disposal. At the same time, the reaction bed is the electronic exchange between the cathode produced a voltage, so that the equipment can supply to the external circuit.

Reaction is a single slot design of microbial fuel cell innovation. Logan pointed out that most of the design of fuel cell response to the two groove-oriented – are the anode and cathode slot slot, slot in the anode in order to maintain anaerobic microbial growth; cathode tank should be maintained at aerobic conditions, electronic and oxygen combine with protons to form water molecules. And a single reaction tank in order to proton exchange membrane to link the two slot, and its function not only in aqueous solution can be divided into two slots, but also to avoid spread to another tank of oxygen. Electrobath trough of the two, other than the force required to provide dissolved oxygen to the cathode, and a single tank of fuel cell micro-organisms can be the way to continuous injection of air into the cathode, thereby reducing the cost of oxygen equipment.

Samples will be completed six months after

In generating capacity, according to Logan said, in the laboratory, the device can generate 72 kilowatts of current, you can drive a small fan. Although the current generated by small, but the equipment is much room for improvement. Invention from the report submitted to the present, Logan’s R & D team has the fuel cell power generation capacity to 350 watts, but Logan would like this value to achieve the ultimate 500-1000 watts. Such as maturity of the technology can be mass-produced microbial fuel cell power generation capacity will be greatly improved, and Logan believes that it can generate 500 kilowatts of the stability of current, about 300 family’s electricity consumption. Logan plans to build a large-scale microbial fuel cell sample, is expected to be completed six months later.

Application prospects

Although the device’s energy output is relatively low, but Logan said they are continually improving the technology, I believe that it can be used in small-scale sewage treatment factory. It is said that the device can also be used to deal with livestock waste water and waste plants, but also can be used in food-processing plants and even manned space inside.

Logan pointed out that as long as it is a place rich in organic matter can be the use of such batteries. However, the microbial fuel cell is the best use of sewage treatment, sewage treatment plant if the use of such equipment, so they can waste water treatment side of the side of power generation, and thus greatly reduce the cost of sewage treatment. Wastewater treatment plant to maintain the normal operation is a very high cost of things. Both developing countries and industrialized countries, wastewater treatment at the same time, the new generation fuel cell technology is very attractive. According to statistics of the U.S. National Development Committee, the United States need to address each of the 33 billion gallons of domestic sewage, the treatment cost about 25 billion U.S. dollars. Most of the cost of almost all spent on the maintenance of treatment plant operation of the energy required, so that if the microbial fuel cell can reduce costs and improve efficiency of electricity generation will be a huge savings for the wastewater treatment expenses.

For the majority of serious pollution of the developing countries, this technology is particularly useful because it can not only purify the water quality, disposal of refuse, while the power generated. Separate from the power this context, the Government has sufficient reason to retain the building and a sewage treatment plant. If the technology can promote the commercialization, waste or sewage treatment will be the country’s money-spinner rather than a heavy burden.

David – University of Toronto is a scientist, he estimated the energy potential in wastewater is 10 times the cost of processing. Logan believes that as long as they can use the potential power of 1 / 20, a sewage treatment plant can be resolved on the cost of sewage treatment.

Microbial fuel cell can also be used to deal with food-processing plants and farms, especially pig farms in the wastewater, in the past, to deal with these unpleasant stench of sewage expensive. NASA also is developing a similar technology, manned space flight in astronauts living in the garbage into energy.

New type of fuel cell materials have emerged

With the world’s fuel cell technology continues to develop, a new type of fuel cell materials continue to emerge, the world’s many well-known companies have also added to the fuel cell component of the study.

DuPont to develop and provide advanced materials for fuel cell components, including Nafion perfluorocarbon membrane and engineering polymers, used in proton exchange membrane (PEM) fuel cells. In 1980 the company began producing Nafion membrane, the current production capacity of 200,000 square meters. Nafion membrane electrolyzer placed as cathode barrier material, the use of hydrogen in the anode and cathode of the oxygen, after the completion of Nafion membrane electrochemical reaction, resulting in the release of ion-exchange effect of the electronics, electronic circuits to form an external current. Reaction process, the hydrogen ions through the Nafion membrane and oxygen ions into the water. DuPont’s Nafion membrane, and engineering materials have been applied to space flight. Now, more than 50% of the PEM fuel cell component materials provided by the DuPont Company.

Celanese Corporation and Honda Motor Company of Japan, to develop automotive fuel cell polymer membrane and the membrane electrode assembly (MEA). MEA by the solid polymer membrane and the catalytic electrode composition. Celanese Corporation successfully developed Polybenzimidazole high-temperature polymer membrane for MEA, its operating temperature can be as high as 180 ℃, and the traditional work of the fluorine resin film temperature of 100 ℃.

Ballard with Victrex company develops and manufactures PEM fuel cell using sulfonated polyether ketone polymer chain containing plasma, high-performance film is expected to reach production capacity of 50 tons / year, may be used to manufacture 100,000 membrane for automotive fuel cell use . Stanford Research Institute also developed for direct methanol fuel (DMFC) using polymer membrane for portable facilities. Motorola also with the Los Angeles National Laboratory to develop portable electronic facilities for DMFC membrane.

At present, the cost of fuel cell catalyst for the equivalent of 10 years ago 1 / 20, so as to fuel cells competitive with existing energy foundation. It is predicted that the end of this century, fuel cell industry is expected to reach sales of catalyst emissions from vehicles sales catalyst.

Battery “heart”

(Trackback: http://www.best-laptop-battery.co.uk/blog )

Hubei Province, electric cars in the “heart” – fuel cell research engine was a major breakthrough. Wuhan University of Technology before fuel-cell engine group revealed by the National Fuel Cell Engine sentinel laboratory testing, our province developed their own battery 25 kilowatts, “the heart”, “jump” out of the leading domestic level. 115 kg weight group will be the “heart” of Shanghai Tongji University, made a special trip to the national fixed-point tested by the laboratory tests, 3 hours, 5 stood for the “final exams” passed. Cold-start from zero to full load operation, only 8.1 seconds. It is not only “feel” strong and continued strong in the full power of 25.11 kilowatts test cases, the continuous and stable operation of 30 minutes, current, voltage fluctuations do not, the two tests, such as the two horizontal lines, on-site testing personnel even referred to as the “true cattle. ” The main points – more than the power density targets in 2005 the U.S. Department of Energy goals to reach the advanced international level of synchronization. Expert evaluation, this small size, high efficiency of the “heart”, especially suitable for automotive power. This means that our province in the study of electric vehicles took a key step. In 2002, Dongfeng Motor Corporation 1000万元funded, with Wuhan University of Technology to develop fuel cell vehicles, the Provincial Science and Technology Department, Wuhan Economic and Technological Development Zone has invested 1.5 million yuan, respectively, for their support. At present, the project has made significant progress. Equipped with the “heart” of the car-type features like cars, a total of 500 kilometers running test, the stability of the speed of 80 km / h, maximum speed of 110 km / hr.

Scientific experts believe that fuel cells will be in our province and a new bright spot in a high-tech to spur the development of a number of new industries.

In 2006 the first fuel cell vehicles to drive onto the city bus to the streets

September 16 Science and Technology Commission was informed that from the city: In 2006, the first fuel cell vehicles to drive onto the city bus to the streets; 2008, Shanghai will have more than a new type of environmentally friendly vehicles such component model car fleet, services the Beijing Olympic Games.

Fuel cell vehicles using hydrogen as energy source, non-polluting, low-power, low noise. Since 2000 the city was listed as a major scientific and technological project, its research and development process of concern, concept cars, “beyond those on the 1st,” “beyond those II” has been published.

Why fuel cell vehicles into the first bus use? Experts explained that the fuel cell vehicle is an epoch-making changes in the automobile industry, the development of the high cost of “expensive car” directly into the market is clearly unrealistic. In before the official commercial operation, fuel cell vehicles need to cultivate a view through the market, the need for government procurement to support the bus is a better choice. At the same time, fuel cell vehicles need to support the construction of hydrogen refueling station, a fixed bus route, just building a small number of hydrogen refueling station can be, easy to operate.

Tongji University Automotive Institute Professor Yu Zhuoping, executive vice president of the Shanghai fuel cells made of the idea of the automobile industry. 2006 to 2007, Shanghai will have 100-class production capacity to form the model team, the construction of several hydrogen refueling station; in 2008 by the year 2010, will have production capacity of 1000-level, the composition of commercial fleet operators, the construction of several Hydrogenation of 10 points; in 2011 to 2015, will have production capacity of 10,000 level, the achievement of regional business, and the construction of hydrogen refueling station 100. Experts conservatively estimate that by 2020 fuel cell vehicles will reach the whole country 2.5 million, accounting for cars for more than 6 percent.

It is learned that the fuel cell bus project has been funded the United Nations in particular, with a total funding amount of 100 million yuan. Similar projects in Cairo, Egypt, India, New Delhi, Shanghai and other Chinese cities in six developing countries at the same time. Some developed countries on the development of fuel cell vehicles are also very important to use. Volvo has developed two fuel-cell double-decker bus has been running in Berlin, 2012-2015 years Ford plans to achieve its commercial fuel cell vehicles, and in 2010 the Japanese planning to have 50,000 fuel cell vehicles and 500 hydrogen refueling station.

With the new fuel cell will use to take off

(Trackback: http://www.best-laptop-battery.co.uk/blog )

“With its features suited to the emergence of new uses, the application of fuel cells will become more and more widely.” September 12, 2004 to 14 in the United States, held in San Francisco on the portable devices of the International Conference on battery “Portable Power Conference and Expo”, the Toshiba Fuel Cell R & D person in charge said the voice of their own. The advantages of fuel cell unit weight of the energy density of current rechargeable battery 5 to 10 times, but it also has its weaknesses, show that the output power density of the instantaneous current output low. To solve this problem, many people on their portable devices as the main power supply is not overloaded and have had a doubt. In response, Toshiba Corporation is responsible for direct methanol fuel cell (DMFC) development of parts of the display material mains, Fumio Ueno, chief engineer on the popularity of their views on fuel cells.

In his speech he said that Toshiba is stepping up its development of three kinds of portable devices for fuel cells, which are for notebook computers increased power density of the active DMFC, such as pocket-sized mobile phone charger for small active DMFC, surface to portable music players and other devices of the passive DMFC.

Do not add pumps which can be added to the fuel cell unit of the passive methanol fuel cell output power density is expected to be low. This passive type fuel cell is not applicable to GSM mobile phone seems like the need for high-power current pulse-based equipment. But more suitable for high current does not need to work on the portable music player and so on. “In the low current, but users are troublesome charge, in the face of such equipment, with high energy density fuel cells have been useless. Fuel cell energy density than the lithium-ion rechargeable battery. This will significantly eliminate the user from time to time to worry about the shortage of battery capacity. ”

The low power density fuel cells, should be excavated in accordance with its characteristics corresponding purposes. “For example, intact in order to replace the current mobile phones use lithium-ion rechargeable battery may be very difficult. On the contrary, should the equipment is not yet available, the use has not yet appeared when to use fuel cell” (Fumio Ueno). As lithium-ion rechargeable battery with the camera body of a VTR (video camera) the appearance of the equipment and the expansion of the application, like the advent of the new equipment will greatly promote the application of fuel cells.

Referring to the new use, the Bluetooth headset the most cause for concern. “Bluetooth support for headset power consumption is very small, There is nothing to the headset and charging users a more troublesome matter. If the passive-type fuel cell mounted on the headset, it can be used for a long time. A reduction of the replacement battery or charger trouble “(Fumio Ueno). The current use of headphones into the rechargeable battery unit weight energy density of the fuel cell 1000Wh/kg, then probably use the time to achieve the current 3 to 5 times. In fact Finland’s Nokia is equipped with fuel-cell prototype of the Bluetooth headset. With the advent of fuel cells, which in turn promoted the low-power, want to ensure that prolonged use of equipment.

Fumio Ueno In his speech after the end of the common with other speakers participated in the panel discussion. Actively promote the development of fuel cells for portable devices Toshiba has become the focus of attention will also field questions focused on who Ueno. Ueno by answering a question by depicting the future of rechargeable batteries: “Looking back, nickel-cadmium, nickel hydrogen, lithium-ion battery, such as various types have come out in succession. But without a battery will completely disappear. Each cell are most suitable for it areas continue to be used. In view of this, even if the fuel cell on the stage, lithium-ion will not disappear, will continue to use different application “, meaning that the proper and best use is the most realistic idea.

Professor Yu Zhuoping Shanghai fuel cell vehicles on the industrialization of the idea

September 16,’2004 Shanghai to exchange the development of fuel cell vehicles will be ‘held. The meeting next year, Shanghai will be the realization of fuel cell vehicles more than 10 small-volume production vehicles, the first hydrogen refueling station will be built at the same time.

At the meeting, our school, executive vice president of Automotive Institute Professor Yu Zhuoping Shanghai fuel cells made of the idea of the automobile industry. In accordance with national long-term development plan, by 2020, cars in China increased by 5 times than now, reaching 100,000,000 3 10,000,000, while traffic to the growth of oil consumption control in less than 2 times. To achieve this’5: 2 ‘type of non-balanced growth, the only way to speed up energy-saving and clean energy industries of the pace car. 2006 to 2007, Shanghai will have 100-class production capacity to form the model team, the construction of several hydrogen refueling station; in 2008 by the year 2010, will have production capacity of 1000-level, the composition of commercial fleet operators, the construction of several Hydrogenation of 10 points; in 2011 to 2015, will have production capacity of 10,000 level, the achievement of regional business, and the construction of hydrogen refueling station 100. If all goes well, by 2020, fuel cell vehicles with traditional internal combustion engine will have the same competitive car and become the mainstream car market.

Fuel cell vehicles using hydrogen as energy source, non-polluting, low-power, low noise. Since 2000 the city was listed as a major scientific and technological project, its research and development process of concern, the concept car ‘than those on the 1st’, ‘beyond those II’ has been published. It’s the third generation – ‘beyond the Route’ will be the driving force for the platform to receive the acceptance of science and technology. Compared to the previous two generations, and once again ‘downsizing’ of the ‘beyond Route’ to achieve the key components of the modular design not only greatly improved reliability, there are also in the energy-saving performance for the bulk of production to lay the foundation. Next year, with the ‘go beyond the 3rd’ out like cars, fuel cell vehicles in Shanghai technical reserves will also be stage ends.

Lithium-ion battery industry competitive analysis: China, Japan and Korea one-third of the world

The world’s lithium-ion battery industry in recent years through the development of China-Japan-South Korea basically formed the pattern of one-third of the world. China, South Korea, Japan, in lithium-ion battery market, competition can be said to be unique, the pattern of one-third of the world will remain a considerable period of time.
 
South Korea

South Korea in the field of secondary batteries based on far less than China and Japan, but South Korea’s advantage in recent years in its consumption of IT and mobile terminals, such as strong growth in product areas. In 2002 global sales of Samsung mobile phones 42.3 million units in 2003 to reach 55 million Taiwan. In mobile phones, flat panel display areas such as Samsung, LG and other Korean brand’s thunder has been obvious over the Japanese enterprises. The lithium-ion rechargeable battery has become the mobile phone, notebook, PDA and other mobile consumer electronics the standard power supply, sold through its own advantages, South Korea’s lithium-ion battery industry is enough to let the Chinese and Japanese counterparts envy. Korea have said that in the IT fields through the use of leading-edge, South Korea sooner or later will replace Japan as the world’s largest manufacturer of lithium-ion batteries.

However, in the lithium-ion battery manufacturing equipment, raw materials and other components, there are currently more than 80% of South Korea to rely on imports, which would weaken the South Korea in the industry’s long-term competitiveness. At present, the South Korean government is vigorously promoting its own lithium-ion battery to form a complete industrial chain and competitiveness.

China

Compared to South Korea and Japan, China’s advantages can be summed up in three aspects: First, the manufacturing costs low. China has cheap and abundant labor resources, you can use human-based semi-automatic production line, in order to adopt low-cost competitive strategy. It can be said that in addition to the expansion of the scale, the world’s lithium-ion battery market, the rapid decline in prices in recent years, the basic from the pull of China’s enterprises. Secondly, China has the world’s largest consumer market. Third, China’s lithium-ion battery has become a relatively complete industrial chain, in the lithium-ion battery supporting material occupied by certain advantages.

Disadvantage, the Chinese companies is significantly less than the development of core technologies, in order to not be controlled by others and being accused of infringement, is still technically innovative Chinese enterprises need to continue efforts. In addition, Chinese enterprises generally smaller and lack of experience in international development.

Japan

Japanese lithium-ion battery business is the high cost of the competitiveness of Japanese companies and the main reason for decline in market share. However, the core technology in Japan than in China and South Korea still has a distinct advantage. In addition, lithium-ion batteries in Japan and South Korea is similar to the industry, the basic are under the Japanese electronics giant companies in the market channels, to capture the consumer and mobile electronics applications, such as trends and response to changes in the market’s ability to market risk is obviously much higher than China’s enterprises.

In any event, the competition in Japan and South Korea is conducive to continue to promote the world’s lithium-ion battery industry and sound development of technological progress.

The rapid rise of China and South Korea

Lithium-ion batteries from Sony in 1992 by the beginning of commercialization, the world’s lithium-ion battery industry which dominates the fundamental from the Japanese by the year 2000, Japan accounted for battery production for more than 95% of the world. In recent years, with China and South Korea’s rapid rise, Japan itself has been the pattern of gradually breaking the Japanese lithium-ion battery market share fell to less than 70 percent now, the world’s lithium-ion battery industry in Japan and South Korea two-thirds of the world pattern has been formed.

South Korea: Global market share of 18.3%

South Korean lithium-ion battery manufacturing business began in late 1999, despite a late start, but the help of South Korea in the consumer and mobile electronics industry advantage to Samsung SDI, LG Chemical and other companies on behalf of the South Korean lithium-ion rechargeable battery industry developed rapidly. South Korea in 2000, only lithium-ion battery production 14 million, accounting for only 2.5% of the global market. South Korea in 2002 production of lithium-ion battery breakthrough 100 million to 102 million, the market share rapidly to 12.8% in 2003 lithium-ion battery production in South Korea more than 200 million global market share reached 18.3%.

Government attaches great importance to South Korea Li-ion battery industry, from 1997 to 2002, the South Korean government a total of rechargeable batteries for the R & D expenditures of up to 465 million U.S. dollars.

Samsung SDI is the South Korean lithium-ion battery industry leader in South Korean lithium-ion battery is the rapid expansion of industry in miniature. 4 quarter of 2002 the monthly SDI to only seven million, in April 2003 with the investment after the new plant 108,000,000,000 greater capacity four production lines of being completed and put into production, Samsung SDI has been the current month to more than 14 million only, Samsung SDI announced that 2005 will reach 23 million per month -2500 goal of 10,000, ranks among the world’s top three series.

LG Chemical is Japan’s second largest manufacturer of lithium-ion battery, the current monthly capacity of 7,000,000. Is currently preparing to expand its market size to more than 15 million per month. 15 million per month is considered the acceptable profit margin can be the smallest production capacity.

SKC South Korea’s third largest lithium-ion battery manufacturers, the company’s main products for the polymer lithium-ion batteries, on the current capacity of 1.25 million. In September 2003 with the new factory production line put into operation one after another, SKC’s to 2005 per month are expected to increase to 3,000,000 10,000 -500.

In addition, is considered the next generation of lithium-ion battery Lithium-ion polymer battery (LiP) areas, to Samsung SDI, LG Chemical and SKC of the Republic of Korea, represented by the production scale of enterprises are also expanding rapidly. LiP is currently South Korea’s per month to more than four million, is expected to Korea in 2004 of polymer lithium-ion batteries to double the production capacity reached eight million / month.

In addition to Samsung SDI, LG Chemical and SKC, South Korean small and medium-sized lithium-ion battery manufacturers, including Saehan Enetech, Kocam Engineer-ing and e-Squretec and so on, in Korea, domestic consumption and rapid growth in the mobile electronics industry are also being driven by growing up .

China: is rapid growth with

Different and the Republic of Korea, China has been the world’s manufacturing power and batteries, the current battery production and exports are the highest in the world. However, lithium-ion battery industry in China is rapidly growing in recent years has it together. China’s lithium-ion battery industrialization began in the latter part of 1997, through the introduction of a study from independent research and development to the industrialization of the road. In 2000, lithium-ion battery industry is the side of the introduction of the basic side of the stage of exploration. After entering in 2001, with the Shenzhen BYD, Bang kai lithium-ion battery technology, such as the rapid rise of companies, China’s lithium-ion battery industry has begun to enter the fast-growing stage, the output of the average annual growth rate of more than 140%. 2002 lithium-ion battery production in China will further increase to 270 million, the global market share reached 20%. -3 In the next 2 years, with BYD, BAK, Bang kai , our God, Universal, the expansion of production scale Guangyu, China’s lithium-ion battery industry will remain more than 30% of the average annual growth rate.

BYD is China’s largest rechargeable battery and lithium-ion battery manufacturers. Founded in 1995, started in 1998 into the commercial lithium-ion battery manufacturers. In November 2000, BYD has become the first Chinese Motorola Li-ion battery supplier, since the rapid expansion of production capacity. In 2002, BYD Li-ion battery production reached 090 million, second only to Japan’s Sanyo and Sony both companies, the highest in the world and in front of the top three out of the Sanyo and Sony to form a direct threat and competition. At present, BYD Li-ion batteries for the 16 million monthly, with its new plant put into operation Shanghai and Shenzhen factory capacity expansion, the company Nissan is expected to lithium-ion battery from its current level of 500,000 to 1,000,000 , which was close to Japan’s Sanyo.

BYD Li-ion rechargeable batteries in the market success of a very important factor is in accordance with China’s national conditions, to human-based independent research and development of automation and human operator to combine the production line. Compared to Japanese companies in the automation of production lines and high labor costs, BYD’s lithium-ion batteries significantly lower manufacturing costs and become an important challenge to a magic weapon for Japanese companies.

Bang kai Science and Technology set up in October 1999 and at the same time large-scale production of lithium-ion batteries, is one of the few to focus on the production of lithium-ion battery R & D enterprise. 2002 Bang kai production of lithium-ion battery technology to reach 21 million, second only to become the second largest BYD Li-ion battery manufacturers. The current month Bang kai technology can achieve the six million, entered the ranks of the world’s top ten manufacturers.

Tianjin power of God was founded in December 1997, is based on the earliest to enter China’s own technology for lithium-ion battery industry as one of domestic enterprises. After the construction works before and after 3, 2002 and an annual output reaching 12 million, sales of 160 million yuan. Tianjin power of God’s products include cylindrical, square, and three series of polymers, in addition to supply the domestic mobile phone business, but also to the Motorola, Samsung and other international manufacturers supply. At present, the monthly power of God can achieve 4 million, and is actively developing lithium-ion power batteries.

Shenzhen BAK Battery Co., Ltd. is a China with a rapidly growing lithium-ion batteries manufactured star. Bic company’s products for the lithium-ion battery batteries. Lithium-ion batteries usually shell, batteries, and charge-discharge circuit protection devices, such as a few parts, including batteries lithium-ion battery is the most crucial parts, many lithium-ion battery business is through the purchase of imports for lithium batteries ion battery assembly.

Although bic in June 2002 the company began a large-scale mass production, but due to the low-cost competitive strategy, the current monthly production capacity batteries has reached 9,000,000, became the largest lithium-ion battery manufacturers. In October 2003, investment of 250 million yuan bic “Nissan one million lithium-ion battery core projects” in the town of Shenzhen Yong Choi held a groundbreaking ceremony, which includes 200,000 Nissan polymer lithium-ion batteries project, Japan 300,000 births steel projects lithium-ion batteries, Nissan aluminum shell 300,000 lithium-ion batteries Nissan projects and 200,000 item cylindrical batteries. After the whole project is expected to be completed, Nissan will reach one million lithium-ion battery production capacity of batteries and has an annual output value of three billion yuan.

In addition to these enterprises, China has a production capacity of lithium-ion battery the size of the enterprises such as Guangyu international, Cup (World Group), Wuhan, Li Xing, Aucma new energy is also growing up fast.

In lithium-ion polymer battery and power industry, China is also at the forefront of the world. Xiamen Baolong industry with independent intellectual property rights of China’s lithium-ion polymer leading enterprises, currently more than 500,000 per month and is building capacity 3,000,000 / month of new production lines. Another polymer battery manufacturer TCL’s monthly payment can also reach the scale of 300,000. Battery power, the CITIC solid profits UNITA has an annual production capacity of five million when the battery power capacity, annual production capacity of 30,000 150Ah lithium-ion power battery broad battery company in Beijing, is investing to build a 300,000 annual capacity of 150Ah battery The new plant, which has the world’s advanced level and independent intellectual property rights, Lei Tian, Shenzhen’s green power source of chromium fluoride lithium battery solid products, including specifications of 10Ah-500Ah six products have been successfully entered the international market, in a variety of electric bicycles, motorcycles and buses has been the application of the company’s 2002 production of 12 million battery Ah, 2003 the annual output to 20 million Ah.

Japan: feel the competitive pressure

Although still in the lithium-ion battery manufacturer to occupy the top spot in the market, but Japanese companies have clearly competitors from China and South Korea feel the impact of stress and headache. Lithium-ion batteries in Japan’s global market share continues to decline after 2000. Japan in 2000 accounted for 93.9 percent of the global market share has declined in 2002 to 69.4% in 2003, further reduced to 58.2%.

Along with China and South Korea Li-ion battery industry’s rapid growth in 2005 expected to be Japan’s global market share will be below 50%.

Faced with the challenge of China and South Korea, the Japanese lithium-ion battery companies are forced to take measures to cool and change their tactics. To sum up, there are three main aspects: First, to Sanyo and Sony, as represented by patent weapons to exert pressure on Chinese enterprises. Second, Chinese enterprises face low-cost competitive strategy, Japan’s companies are setting up production bases in China, such as the use of low-cost labor advantage to improve its competitiveness, the current Sanyo, Sony, Matsushita and other Japanese companies in Beijing, Wuxi and so on are established lithium-ion battery manufacturing plant. Third, adjust the scale of production. This aspect of the strategy of Japanese companies are not the same. Sanyo and Sony and other major manufacturers continue to expand their scale of production through to try to continue to maintain a leading position, while others such as Toshiba (ATB), NEC and other manufacturers are in varying degrees of competition gradually expanded and turned to lower manufacturing costs and new technology research and development strategy.

In October 2002, Sanyo batteries and Japan reached an agreement to buy Japan’s Sanyo battery GSMT51% stake in a subsidiary. Through mergers and acquisitions, Sanyo to make their own scale of production to further enhance and consolidate the current lithium-ion battery SANYO control 27 percent of global market share and continue to top the global leader in location. In February 2003, the company purchased GSMT basis, Sanyo set up an independent subsidiary of lithium-ion battery manufacturers, and are prepared to invest ¥ 16,000,000,000 to build a factory. Sanyo said the company in 2004 lithium-ion battery output will increase to 50 million.

The world’s second largest manufacturer of lithium-ion batteries by Sony in early 2003, a new lithium-ion battery manufacturing plant, the current monthly production can reach 18 million, and has been reported that Sony has further plans to expand production capacity. Although the world’s first commercial lithium-ion batteries manufactured by Sanyo catch up enterprises, and China and South Korea face the threat of corporate catch-up, but in the field of lithium-ion polymer battery is still leading. At present Sony lithium-ion polymer batteries for 5.5 million per month, accounting for more than half of world market share and intends to further production capacity this year to 6.5 million / month.

Other Japanese companies such as Matsushita (MBI), Toshiba (ATB), NEC Corporation, in the face of South Korean companies from China and the market price of brutal warfare, in the expansion of production scale, the current expansion of basic not easily increase. The fact is that from 1995 to 2002, the lithium-ion battery production 22-fold expansion, but sales revenue over the same period increased by only 7 times. In recent years, lithium-ion battery to achieve an average annual rate of price decline in more than 15%, in the face of such a brutal price competition, the industry believes that in order to profit, the production scale to reach more than 15 million per month.

Lithium-ion battery industry as a driving force for growth and special equipment

(Trackback: http://www.todaybattery.com)

In recent years, rapid development of China’s battery industry. With BYD, as the power of God on behalf of a group of lithium-ion battery manufacturers and the rise of the rapid growth, China’s lithium-ion battery industry has high-speed growth. According to statistics, in recent years, China’s output of lithium-ion batteries to double the average annual rate of growth in 2003, lithium-ion batteries popular in domestic and foreign markets, export 314 million, more than 127 percent growth in 2002, due to the rapid growth of domestic demand, 2003 import lithium-ion battery 354 million, more than 143 percent growth in 2002. Experts predict that over the next few years, with the number of backbone enterprises continue to expand production scale, mobile phones and portable products such as notebook computers continued growth, China’s lithium-ion battery industry will remain more than 30% of the average annual growth rate.

China’s battery industry begun to take shape

In October last year, Global Sources for the supply of domestic battery to do a survey, the survey showed that, at present, China’s battery industry has been of considerable size. First of all, in the field of disposable batteries, China’s output has exceeded the United States and Japan, ranking first in the world. China’s Power Industry Association of the information shows that China’s one-time single-cell capacity of 19 billion, lithium batteries, nickel-cadmium batteries and nickel-metal hydride battery production were 2.2 billion, 10 million and about 500 million. Secondly, the field of rechargeable batteries in the second, China’s production is second only to Japan and South Korea, ranked third in the world, and occupy in the global market share of 12.5%. Judging from the number of manufacturers, China’s large and small, battery manufacturers have more than 2000, mainly located in Tianjin, Jiangsu Province, Shanghai, Zhejiang and other coastal areas of Guangdong Province. However, despite the many manufacturers, but the strength of the difference between manufacturers. Statistics show that 10 of our former battery factory and the production of more than one billion, close to the domestic battery output 1 / 4.

The increasingly fierce market competition, the Chinese battery makers actively involved in the research and development of new products to meet changing market demands, and many products have achieved commercial production. By the consumer electronics, especially portable electronic devices driven by rising demand, the domestic lithium-ion battery manufacturers are developing low-cost, high-capacity lithium polymer batteries and lithium batteries. Reports indicate that Wuhan Li Hing Battery for Bluetooth wireless headset and digital audio players designed a lithium coin cell batteries and micro-prism. Recently, the company also introduced a new type of lithium batteries for low temperature below -30 ° C environment. In addition to research and development of new products, lithium battery manufacturers are also actively expanding production capacity to meet the rapid growth trend. China’s Power Industry Association predicted that manufacturers will rush to get to China’s Li-ion battery production in the next few years to maintain growth momentum, particularly in 2006, China’s output of lithium batteries will be an annual rate of 30% of fast growth.

Lithium-ion battery market demand

Lithium-ion battery for its light weight, high capacity, high voltage, long life and no pollution has been growing rapidly. According to statistics, the global lithium-ion battery has exceeded sales of nickel-metal hydride and nickel cadmium batteries of the sum of the rapid promotion in the market. As the nickel-metal hydride batteries and nickel cadmium batteries gradually shrinking market, mobile phones, digital cameras, PDA and portable video cameras and other consumer and mobile electronics products, as well as the continued strength of lithium-ion power battery applications has tremendous potential for future lithium-ion battery market demand maintain considerable growth. Online prediction of new materials in 2003 -2006 the global lithium-ion battery production scale will reach a CAGR 23.2% compound growth rate of sales income will reach 12.25%; in 2007 -2010 in lithium-ion battery industry will enter a phase of relatively steady growth is expected to scale of production growth rate of 9.85% compound sales growth rate of 5.85% compound.

New materials online Guoqiang, chief researcher believes that further enhance the battery’s energy density and safety of environmental performance and reduce manufacturing costs, research and development of new electrode materials and the manufacture of thinner and lighter lithium-ion battery technology is the industry’s research and development direction in recent years technological progress achieved shows that the cost of lithium-ion batteries still have a considerable decline in the space.

Competition in the market, Li Guoqiang that with China and South Korea to low-cost strategy for rapid market competition, forcing Japan’s second-line a lot of lithium-ion battery manufacturers to stop expansion plans or the market gradually. On the other hand, a leading manufacturer in Japan and South Korea have carried out large-scale expansion in order to maintain a superior position, the scale of mass production in more than 15 million on the growing number of manufacturers. According to Tianjin Co., Ltd. introduced the battery power of God, since the beginning of this year, Tianjin power of God the steady growth of cell production from month to month. In January this year to April of battery products and high start-off to a good start, 4 months ago produced a total of more than 10 million batteries for the Motorola supply about three million, and achieved better economic benefits. In raising Motorola, Bird and other key customers and suppliers supply varieties on the basis of their plans this year to develop a number of multinational corporations large-scale customers.

Process equipment should attach importance to innovation

With the development of domestic battery, battery production equipment in China has been growing enterprises. At present, production support for secondary battery of special equipment more enterprises have more than a dozen. Beijing Seven Star Electronics Corp. CRE electronic automation equipment, general manager of Golden Road branch, said different secondary battery production enterprises of different aspects of technology services industry more refined division of labor. In his view, the industry product manual equipment, semi-automatic equipment, automation equipment, stand-alone products, fewer full-automatic production line manufacturing. The overall technological level is not high compared with foreign countries, product updates slower, generally low grade. ARBIN U.S. companies operating in China in Beijing on behalf of super-Yang also believes that the highly competitive domestic equipment, but only in the low-end products, high-end equipment such as battery test equipment, fuel cell test equipment, high-precision test equipment market by foreign products occupy. In his view, the domestic equipment technology is simple, a serious shortage of investment in research and development is the main reason.

Equipment, funding constraints have become less than lithium-ion batteries in China a major obstacle to industrial development. China’s lithium-ion batteries have been made to achieve the domestic lithium-ion battery market share accounted for 20% of the global market, and have achieved higher profits and the reason why This has been achieved mainly because of low raw materials and processing costs , the majority of Chinese-made battery operated manually, resulting in lower overall processing costs. Li-Quan Chen Chinese Academy of Engineering has pointed out that despite the small lithium-ion battery market in the low-end applications have achieved good results, but the Chinese-made lithium-ion batteries are faced with an important issue, that is, from low-end products used in mobile phones, the transition for high-end products such as notebook computer power supply. Only need a cell phone, and notebook and other high-end products require more than the same battery performance with the use of series-parallel connection. Small battery as a result of domestic production depends mainly on manual operation to complete, making the product difficult to achieve consistent performance. To solve this problem one way, that is, replacement of existing equipment. The production of high-tech products have to import high-tech equipment? Li-Quan Chen does not think so, for example, the use of mobile phone batteries as an example of a square steel, by technology limitations, has been previously imported from Japan in China, some domestic enterprises by changing the production process cleverly solved the technical problems. Practice has proved that China has with the design, processing semi-automation and automation equipment for lithium-ion battery capacity. Li-Quan Chen stressed that to develop lithium-ion battery industry, not only to solve technical problems, processes, equipment used should also pay attention to innovation.

Early domestic battery imperfect equipment, high cost of imported equipment, it is the continuous exploration of the special process greatly reduces the production costs of the batteries to enhance the competitiveness of the product for the development of China’s battery industry to create a new situation .

China’s Li-ion battery production and growth forecast

2000 -2003, China’s lithium-ion battery industries grew rapidly, with an average annual growth rate of more than 140% over the next few years, with BYD, BAK,邦凯, our God, Universal Guangyu, such as the continued expansion of production scale, China’s lithium-ion battery industry will remain more than 30% of the average annual growth rate.

The global lithium-polymer battery production and the growth rate of

Hailed as the next generation of lithium-ion battery Lithium-ion polymer battery (LiP) since 1999, production from Sony since the pace of development has been stronger than ordinary liquid lithium-ion batteries in 2002, polymer lithium-ion batteries have accounted for all lithium-ion battery market share of 7 percent.

Lithium-ion battery

Different direction based on the use of lithium-ion batteries can be broadly divided into portable electronic devices for power supply of small lithium-ion battery and provide an impetus for the transport of two types of lithium-ion battery power. The former have been more perfect technological development, industrial scale a huge concentration of production capacity in East Asia, an increasing trend to gather. The latter is still in the business of start-up phase, liquid packaging power lithium-ion rechargeable battery technology, the research indicates that the level of our country in the world. Electrode materials, however the level of R & D and industrialization of the relatively stagnant, more and more restricted the lithium-ion battery industry in China to further develop the bottleneck.

Fuel cell

Mainly concentrated in the fuel cell to provide power for the transport of hydrogen fuel cell research and to provide power for mobile devices of the methanol fuel cell research both sides, especially for mobile devices such as laptop computers provided by methanol fuel cell research, in recent years the rapid development of large-scale production is about to achieve. Constraints of large-scale practical application of fuel cells is still the bottleneck cost. Because it can effectively address the growing problem of traffic pollution, the use of hydrogen fuel for fuel cell vehicles practical application has been attached great importance to governments.

Recycling is no longer on the 5th on the 7th battery

Environmental Protection Agency was informed yesterday from the autonomous regions, as on the 5th, on the 7th battery production has reached a low mercury or mercury-free production standards, decentralized disposal will not pollute our environment, so the future of the V, the battery will no longer be on the 7th focus on recovery.

It is understood that the past will be used on the 5th, on the 7th battery recycling together, in fact, will not be good for environmental protection, because on the 5th, on the 7th battery production has reached a low mercury or mercury-free, and the disposal will not be dispersed pollution on the environment. To be on the 5th, on the 7th battery together to deal with more trouble, because our country has not focused on the facilities to deal with these batteries, processing technology is not mature. However, rechargeable batteries and button batteries, as a result of heavy pollution, these types of batteries will be recycled by the manufacturers to focus the public should not arbitrarily discarded.

Japan’s energy supply innovation

Japan is a resource-poor countries, the proportion of imports of energy supplies in the larger, so saving energy has been a great effort to resolve the Japanese issue. At the same time, with the development of science and technology, Japan’s energy supply is quietly changing. Peak this summer, the Tokyo gap of electricity to about two million kilowatts. In order to ride out the storm, trying to conserve electricity where Tokyo. Rainbow Bridge Tokyo night light is a well-known King, but the pain this year, relevant departments have to afford to spare, so Rainbow Bridge bright lights for several hours late, and went out early to ease the strain on power supply. Many high-rise buildings in Tokyo lighting decorative lighting to reduce the use of all. The building and operation of civilian air-conditioning are also required from the past 27 degrees Celsius to 28 degrees Celsius.

Japanese life in general there are many auxiliary power supplies, such as energy-saving light bulbs. Ordinary light bulbs with energy-saving light bulbs than not reduce the brightness, power consumption is less, or an ordinary light bulb life 30 times, although the purchase price is relatively expensive, but look at the long-term use is still very affordable. A tiny light bulb from the start, we can see that Japanese energy-saving care and thought. To resolve the issue of energy supply, reducing expenditure is based on reality, and open source is the future. The Japanese government decided in April this year, by 2030 energy demand in Japan’s dependence on oil will be greatly reduced oil supply by the total energy now accounts for 50% to 40%, and new energy sources will rise to 20%. These new energy sources including wind, solar, biomass and geothermal power generation. Tobu Isesaki Line Ota five kilometers northwest of the station, there is a small satellite, which is a new type of residential. A look at the roof will find that all the houses are equipped with solar panels, which is the Japanese Economy, Trade and Industry of solar power generation pilot. Various facilities in addition to solar power, have laid a common wire. During the night, cloudy or not enough solar power, the power company can supply wire; the other hand, the strong sunshine, solar power generation can be exhausted through the wire when the remaining electricity to the electricity transmission company. Located in Tsukuba City, Ibaraki Prefecture, Japan Institute of Advanced Industrial Science and Technology recently completed Japan’s largest solar power system. Area of solar panels together and as big as football pitches, a total of 6500 square meters, using the four kinds of materials such as silicon. Battery insert plate, respectively, in the Institute of buildings and car parks and open space the slopes, a total of 5600, and AC DC variable device 21, the total cost of 8 billion yen (one U.S. dollars approximately ¥ 108) . Its power generation up to 869 kilowatts, and with existing equipment, power generation, power more than 1000 kilowatts of electricity for the use of 300 families, is the crystallization of the latest technology in Japan.

Many of the seaside park in Japan, people can often see beautiful shapes in the rotation of the windmill power generation. They add beauty at the same time, given the park an increase of electricity supply. The northern part of Iwate Prefecture, vol GE-cho, more than 1000 meters above sea level, wind resource-rich, population 8,700, a total of 15 typhoons car. Recently, the Kansai Electric Power Company is also planning the construction of Shimane Prefecture in the large-scale wind power generation base, plans to install 40 Typhoon car. Once completed, there will be Japan’s largest wind power base.

Bio-power generation is a new thing in Japan. April 2003, Japan, vol GE-cho, Iwate Prefecture cow manure power plant first began operation. The cow-cho, 300 specialized households, scattered the 435 sq km, 10,000 dairy cattle feeding. On the use of cow manure power plant 200 cattle manure generation. Livestock production in the base power plant, the construction cost of approximately 2.2 billion yen. GE also plans to use the volume-cho, fermented cow manure to create methane gas produced by fuel cells. Japan’s energy and electricity consumption is taking the same path of sustainable development. Focus on a variety of energy-saving technologies to meet the needs of environmental protection, energy-saving products in the international market has been to enhance the competitiveness of its economic benefits incalculable.

Cell phone lithium battery market outlook

(Trackback: Uk laptop battery Site.)

In recent years, as a result of mobile communications and portable electronic products to flourish, there is increasing emphasis on the quality of batteries, including rechargeable batteries due to the small consumers, which led rechargeable batteries from a wave of industrial investment. According to statistics, the global small rechargeable battery is about the annual production value of 10 billion U.S. dollars, of which the mainstream of the lithium battery products accounted for more than half of it is.

The world for more than 65% of lithium battery shipments are concentrated in Japan’s Sanyo Electric, Sony and Matsushita Electric Works, the three major manufacturers, as a result of excess production companies in Japan, coupled with the lithium batteries in China and South Korea to enter the market continues to get low-cost attack the market, resulting in price decline in the level of lithium batteries is far more than expected, although overall shipments of lithium batteries a small growth, but the result of declining average unit price, making the overall output of lithium batteries about 13.8 percent decline. Outlook 2004, as the market digested the recovery of stocks finished with the phone, the mobile phone manufacturers are forecast to increase shipments by 10% ~ 15%, while the output of lithium batteries is expected to grow 3.8%.

It is worth mentioning that, China’s lithium battery manufacturer BYD, 2003 in the overall shipping capacity of 75 million, has been promoted to the rank of the world’s fifth largest manufacturer of lithium batteries. As for the square type of lithium battery shipments of mobile phones in the request because the trend of thin short, 8mm thickness of more than 2003 products accounted for only about 5%; and mainstream products for the thickness of 6mm, up to 62% share; In addition the thickness of 3 ~ 4mm proportion of the products has risen gradually in 1999 from the rapid growth of 3 percent to 33 percent of in 2003. Outlook 2004, the thickness of 6mm or more products will be gradually reduced to 3 ~ 5mm thickness Yongyue mainstream products in the market.
