Rechargeable battery: From “Made in China” into “Created in China”

Filed under: Uncategorized — besbat001 @ 9:58 pm
Correspond with the main battery, rechargeable batteries, including lead acid batteries, alkaline batteries, lithium-ion batteries, solar cells, fuel cells and super capacitors.
Old China Lead-acid batteries industrial base was very low, only a small prototype of lead acid battery industry. Before the founding of New China, there are only a dozen small factories and workshops producing cells, fewer than 800 people, can produce a battery of motor vehicles and small plates used for maintenance and a small amount of communication with the battery and fixed the battery type. However, annual consumption of 400 tonnes of lead.
Today, our lead-acid battery industry has been essentially consists of a combination of large and small companies with a manufacturing system of. With the energy, transport and communications, the rapid development of pillar industries, mainly for automobiles, motorcycles, electricity, telecommunications and other industries, lead acid batteries in the period expansion of development, the market expanded.
“The rapid growth of the auto industry and policies on the renewable energy industry, strongly support, industrial electronics technology continues to advance, leads, lead China-acid battery industry and the international advanced level will gradually reduce the gap and lead to the China-acid battery industry show the dynamics of rapid growth. Jin-Liang Wang said.
In recent years, electric vehicles such as the development of new energy vehicles, such as lead acid battery industry has been developed. 1998-2004 average growth rate of annual Chinese production of lead acid battery from 17.8% in 2004 reached 30%. It is anticipated that with the increasing number of cars, this proportion will continue to increase. On the export side, China’s average growth rate of exports of lead acid batteries will not be below 20%, the share of exports will increase gradually. In 2009, China’s lead-acid battery growth average annual sales of about 15%, annual production should reach 130 million KVA -14.0 billion, sales revenue of 65 billion from -700 billion.
With centuries-old lead acid batteries, compared to lithium-ion battery can be ready to tell the little brother, but this “little brother” has huge potential and future.
In 2001, a Liuxun old days when he was in Shanghai, visited the 863 electric cars, Wan Gang, head of major projects. In conversation, he repeatedly expressed strong feelings with his own wishes - “I hope lithium-ion batteries a chance.”
The old man is to be affectionately nicknamed “the father of lithium batteries in China,” Li-Quan Chen, Chinese Academy of Sciences. 863 plans as a national special person in charge of secondary lithium batteries, Academician Chen, Research of the lithium battery from China, development and industrialization of the formation of groups have made an outstanding contribution to build solid foundation. In 2000, after learning that the lithium batteries in the “15″ 863 major projects planned electric car is not regarded favorably, Li-Quan Chen can not stay in place. In his warning calls running under the steel of 10,000, against all odds, lithium-ion battery successfully screened 863.
From that point, the search for Lithium battery and development in the climax: “15″ and the “eleventh five” year period, the electrode main positive and negative and electrolyte materials, has made key localization of production. In 2006, Chinese production of lithium-ion batteries to reach global production of lithium-ion batteries to 41% in 2008 to 50%. In mobile phones and MP3 battery market, Chinese products account for over half the market share.
“Our lithium-ion battery electric vehicles may be technologically competitive advantages in developed countries, developed and lacks the resources and market benefits. Therefore, focus, focus on research, rapidly advancing industrialization lithium ion battery for electric vehicles is in line with the strategic choice of national conditions of China is an important means for ensuring energy security. ” Academician Li-Quan Chen said. At present, China has become the lithium-ion battery, one of the three main producing countries. Only a small lithium-ion battery, China has achieved an annual output of 2 billion euros, technical level with those of Japan.
It is noteworthy that our country in alkaline batteries, solar cells and other areas have also made considerable progress. China started research on solar cells in 1958. 80 in the late 20th century, the interior has introduced a number of production lines for solar cells, the Chinese have the production capacity of solar cells from the three originals of hundreds of small factories kW blow four 4.5Mw plants. In 2002, the European market, especially the German market, the rapid amplification and Wuxi Suntech Power Co., Ltd., have expelled and ultra-conventional development of photovoltaic industry in China has brought unprecedented opportunities for development and demonstration effect. At present, China has become the world superpower solar cell manufacturing in 2008, production reached 2000MW, more than one quarter of world production. Let market forces to promote energy efficiency and solar energy conversion, the level of continuous improvement of production technology, materials technology, crystalline silicon production is a first, and gradually breaking the monopoly foreign countries.
Sealed maintenance free batteries and without sulfur dioxide, the battery can be stored and used in any direction, etc., in the provision of postal services and telecommunications, energy sets, computer UPS Power Supply Devices of lighting and other occasions widely used. In recent years, Jiangsu pairs of Golden Group, through technical innovation, has developed a communication with the valve-regulated batteries, gel batteries and other products, covering 65 countries and regions, telecommunication batteries made in dozens of countries Europe and the United States and other authentication for network access, used by many state public-sector markets for standby power.
In the field of alkaline batteries, batteries nickel metal hydride in China producing nearly 10 years has been on an upward trend, from 1996, less than 20 million development in 2007 of over 1.2 billion individuals; Ni-MH batteries have an important scientific research in space applications products. In the field of technology, Harbin Institute of Technology Professor Wang first production Jishan type nickel foam, dry powder electrode technique, which greatly promoted the progress of the industry.

Batteries and Environmental Protection

Filed under: Uncategorized — Tags: , — besbat001 @ 8:56 pm
The potential contamination of used batteries has aroused widespread concern in the community. China is the world’s number one dry battery producing and consuming countries, our data show that China currently has more than 1,400 battery manufacturers in 1980, the volume of production of dry batteries surpassed the United States and the largest in the first world. In 1998, production of dry batteries in China amounted to 14 billion, while the same year the total world production of dry batteries is approximately 30 billion euros.
Such a large quantity of batteries, making it a big problem to light and that is how to make so many batteries does not affect the pollution of our environment. According to our survey, used batteries containing heavy metals and waste acid, waste alkali and electrolyte solution.
If you arbitrarily discarded batteries will destroy the corruption of water, erosion of our cultural survival and the earth, our environment is facing a huge threat. If any of the cell 1 in the soil and rotting, it’s toxic form a square meter of land to lose value, throw a coin battery in water, which contains toxic substances that have killed more than 60 million liters of water pollution, equivalent to a person’s life, water, batteries containing heavy metals cadmium, lead, mercury, nickel, zinc, manganese, etc., in which cadmium, lead, mercury is a great mistake to substances in the body. Nickel, zinc and other metals, although to a certain range of concentration is a useful material, but in the environment over the limit, but also harm the human body. Waste batteries leaking heavy metals can cause rivers, lakes, sea and other bodies of water pollution, endangering the survival of aquatic and water consumption, an indirect threat to health human. Waste acid, waste alkali and so on could contaminate the electrolyte solution so that soil acidification and salinization, which Decker around us like a bomb. Therefore, collection and disposal of batteries is very important, if disposed of improperly, may be placed on the ecological environment and human health, cause serious injury. Randomly throw used batteries are not only pollute the environment, is also a waste of resources. Some people forget one account to the country’s annual production of 10 billion batteries, the annual consumption by 156,000 tonnes of zinc, 226.000 tonnes of manganese dioxide, 2080 tons of copper, 27,000 tonnes of zinc chloride, 79,000 tons of chloride ammonium, 4.3 million tons of carbon rod. Despite the advanced technology has given us the right direction, but the phenomenon of pollution in China’s battery is still not optimistic. Most waste in courtyards of China has been mixed with used batteries together in the soil over time, after the battery into decay, leaching of heavy metals, the two agencies could contaminate groundwater, they can contaminate soil and finally through a variety of ways to enter the human food chain. Biological uptake of heavy metals from the environment by biomagnification in the food chain, class by class in higher organisms tens of thousands of times richer, and then enter the body through the food chain, and economies Organ cause chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning.
The batteries are generally divided into disposable batteries and rechargeable batteries. Disposable primary batteries, including zinc-manganese batteries (zinc and manganese dioxide) batteries containing mercury zinc (zinc oxide and mercury) and lithium batteries and several other categories. Rechargeable batteries are the main cadmium - nickel, iron - nickel, zinc - silver, zinc - air and lithium - iron sulfide and lead acid batteries and so on. Our daily life is the most frequently used zinc-manganese batteries and zinc-mercury batteries, leaving the farm pollution is mainly caused by mercury (Hg) and cadmium (Cd).
The toxicity of mercury
Mercury, which are commonly called “Mercury is liquid at room temperature, the material, can keep the battery in zinc oxide cathode, this approach to improve the shelf life of the battery. Thus, when the zinc previously used in batteries to be very cloudy almost all do a certain amount of mercury preservative. However, the chemical combination of mercury and mercury neurotoxicity of endocrine, immune system, also have a negative effect, it will trigger problems for people with speech, unsteady gait, limb paralysis, leading to generalized convulsions , mental disorders and died.
For years, China’s production of dry batteries, it is necessary to attach a toxic substance - mercury or mercury compounds. China mercury in alkaline batteries up to 1% ~ 5%, 0.025% neutral dry-cell batteries, dry batteries annually for the production of tens of tons of mercury amounted to much. With advances in technology, the battery began to implement a low-mercury and mercury-free alternatives to the mercury surface of fluoropolymers FORAFAC to prevent corrosion of zinc has achieved good results.
The mercury batteries disposed of untreated overflow from the battery slowly in soil or water, then under the action of microorganisms, inorganic mercury can be transformed into methylmercury, meeting in the body of fish, human consumption of fish such as methylmercury, enters the cells of the human brain, the nervous systems of people have been seriously damaged in severe cases would be crazy to death. Well known Minamata disease in Japan is caused by methylmercury.
The toxicity of cadmium
Cadmium is a trace element necessary for the human body, the body of newborn babies, and there is no cadmium, but increased with age, and gradually accumulated. Cadmium with renal toxicity, which caused kidney damage is irreversible. At the same time, after a kidney damage may also be secondary osteoporosis, osteomalacia and fractures. In 1993, the International Union Against Cancer will be set at IA carcinogen cadmium level. For these reasons, many developed countries have recommended a ban on the use of nickel-cadmium batteries and nickel-metal hydride battery has been replaced by nickel-cadmium batteries, avoiding the use of cadmium. In China, the vast majority of battery manufacturers still use cadmium as raw materials for manufacturing the battery, the battery being further increase the dangers. Affected by the long-term consumption of cadmium from water and contaminated food can lead to bone pain and disease, cadmium in the body, causing skeletal deformities, osteomalacia, and in the severe form of natural fractures, and even death.
The toxicity of manganese
Excessive levels of manganese accumulation in the body can cause neurological dysfunction, an early manifestation of an integrated sexual dysfunction, the emergence of more heavy monotonous speech, sad expression, emotional indifference, accompanied by psychological symptoms .
Lead toxicity
Driving a major role in the nervous system, hematopoietic system, digestive system and liver, kidneys and other organs, can inhibit the synthesis of hemoglobin metabolism, but also directly on the mature red blood cells, for infants, children much younger, it will lead to physical development of children, a chronic lead late in the mental retardation of children first.
The toxicity of nickel
Nickel powder dissolved in the blood, to participate in the movement of the body, with a high toxicity, may damage the central nervous system, causing abnormal blood vessels, severe cases, cause cancer.
The toxicity of zinc
Zinc is an essential element of the human body, less toxic, 1000 mg of zinc sulfate orally only to those with acute intoxication, but inhalation of dust zinc oxide may cause poisoning. The symptoms include generalized fatigue, muscle pain, difficulty breathing, vomiting, diarrhea, severe heart weakness, prostration, convulsions, death. Zinc sulphate, zinc chloride penetrated the mucous membrane of the skin may produce dermatitis and ulcers. Zinc to fish and aquatic toxicity of the toxic people, if the requirements of water quality for fish in the water content of zinc per liter should not exceed 0.1 mg.
Recycling of waste batteries
Waste batteries may be small, large Queshen cons. However, due to pollution, waste piles are not as waste, air and water pollution, as would any sensory think she has a big secret, so do not receive the attention. At present, battery production and consumption of China to become a great country, and the batteries of pollution is an urgent need to address a major environmental problem.
According to environmental experts, recovery of waste batteries per 1000 grams of metal, which are 82 grams of mercury, 88 grams of cadmium, we can say that eliminating the recycling of waste batteries s The address not only the sources of pollution, but also to achieve the recycling of resources. In developed countries the recycling of batteries and use very seriously. Many countries in Western Europe, not only in stores, but also directly on the street are equipped with a special box for recycling batteries and accumulators are 95% of the material can be recycled, especially in high recovery of valuable metals. Such as foreign secondary lead industry developed rapidly, lead to short-term 55% of production comes from reclaimed lead. The secondary lead industry in the treatment of the regeneration of waste lead-acid batteries account for a substantial portion. 100 kg of waste lead-acid batteries can be recycled 50 to 60 kilograms of lead. Cadmium batteries for the regeneration of technology waste treatment abroad, have been more mature to deal with 100 kilograms of waste recycling cadmium batteries of about 20 kg of metal cadmium, mercury batteries are mainly used to treat environmentally sound ways to prevent environmental pollution. However, there is in this area of management rather low.

Digital Camera Battery option

Filed under: Uncategorized — besbat001 @ 8:07 pm
First, the classification of battery for digital camera

To understand a thing that is clear, it is necessary to be there in an orderly manner. Currently on the market, digital cameras, batteries used in three main categories, namely, alkaline, nickel-hydride batteries, metal and lithium batteries. Here I would like to tell us about the three types of batteries and their advantages and disadvantages.

1, alkaline

The alkaline batteries that we live in the most commonly used as an ordinary battery, it is about 7, 5, 1 and therefore the different models currently in use alkaline batteries commonly used in digital cameras are on the 5th of alkaline batteries.

Alkaline batteries advantages: easy to use alkaline batteries, lower prices, other forms and the price is very high.

Alkaline batteries Disadvantages: Can be recycled, an investment of time was low, but the combined use of its high cost.

Alkaline NOTE: If a long period of not using the camera, alkaline batteries should not be placed in the machine, it takes too long to be out of a number of internal alkaline batteries have a corrosive liquid, flowing into the liquid if the device very easily lead to component damage.

2, Ni-MH battery

Ni-MH battery also known as hydrogen fuel cells. He is currently on the market for users of digital cameras are most widely used batteries, alkaline batteries with General Motors, the size of models is basically the same with alkaline batteries.

Advantages of Ni-MH battery: You can load, the general-MH battery can be recharged 1,000 times or more, versatility, compatibility issues and is not exactly outside the alkaline same model can be used to replace the another.

Ni-MH battery Disadvantages: the MA itself, with the voltage-MH battery life is less than alkaline batteries, alkaline batteries and an investment of time that many counterfeit products on the market.

Ni-MH battery Note: Ni-MH battery charging should be noted, should not be too long to pricing, use the charger is also very important, if we find the process of charging the battery at temperatures warmer sont élevés, il devrait immédiatement débrancher le chargeur de ne plus réclamer.

3 lithium batteries

Li-Ion battery is a new generation of rechargeable batteries is not only light weight, power consumption and high. Electronics and digital mobile power is preferred.

Benefits of lithium: 30-40% lighter than other batteries, but energy is higher at 50-60%, almost no memory effect, longevity, and durability far superior to metal hydride batteries.

Lithium batteries Disadvantages: the price of lithium batteries are very expensive, is a hundred times more than alkaline batteries, the investment of users is high, and manufacturers of digital cameras differ from lithium batteries is basically impossible ordinary (Note: a manufacturer of digital cameras may be a Nokia Universal models of batteries for mobile phones), if outside, under the power of light is difficult to find alternatives.

Lithium Battery Caution: Lithium battery is less than the first two batteries “robust”, so be careful not to prevent falls from heights, underground, another lithium battery to preserve the environment should pay attention to moisture particularly in the south of the rainy season.

2, battery digital camera option

First, users using a digital camera to buy the battery, when to see your own digital cameras equipped with what is used in the battery. If it is on the 5th battery or the battery 7, and you do not often users of digital cameras, I recommend that users use good quality alkaline batteries. Because alkaline batteries not only cheaper (better battery Nanfu price per pair only about 5 yuan), but also higher than nickel-hydrogen batteries power the strong, even if the batteries are exhausted in use, it can be easily anywhere in has bought a small shop.

For frequent users of digital cameras on the 5th or the 7th battery users, it is recommended to purchase batteries, nickel metal hydride battery. Although the once high investment, but the cumulative cost is lower than alkaline batteries and can be common with ordinary alkaline batteries, even if the battery is out there, you can temporarily purchase the same type of alkaline batteries. However, the current market, types of Ni-MH rechargeable batteries is very high, energy consumption from 600 milliamperes to 2300 milliamperes, the voltage of 1.5 V to V n, while the user how to choose what to buy?

Below, I will be a choice of Ni-MH rechargeable batteries noted to share with you.

1, users usually buy the hydrogen battery, the voltage is often neglected issue. For example, a rate of 3.6 V, 1200 mAh and a 7.2-volt, 900 mAh battery compared to 1200 milliamps many users to choose the battery, because the more mA, indicating that it is the release of electricity per hour plus plus. But this is not the case for this is the case between the use of time alone is, in fact, a second battery, that is, 7.2 volts 800 milliamps of this piece some more abundant battery, using words not appropriate for example, called this “language skills”, although the output per unit time is small, but because the battery voltage is much higher than the first, if the battery life should also more stronger than the first. Therefore, the total output in mA or less the same circumstances, it is recommended to buy a higher voltage hybrid rechargeable batteries for longer periods of time (of course, must also refer to the machine with nominal dimensions of voltage).

2, hydrogen fuel cell “essential nature” In fact, its use in batteries, the batteries are still relatively good Japanese manufacturers such as Sanyo, Toshiba, Panasonic, etc., while household batteries at R & D are still in the second rate -. Therefore, under the conditions permit, the user should give priority to the purchase of imported batteries to rechargeable batteries. Of course, in addition to the above marks Japan’s hydrogen fuel cell, the facts on TCL, patriot, DEC is in constant good brand. Their low prices are also a wide range of consumer groups.

According to the experience of the author, we recommend using 1800 milliamps of Ni-MH rechargeable batteries currently on the market in 1800 milliamps of hydrogen fuel cell is the most cost-effective products. The brand depends mainly on the economic level user-specific and needs, it is better to buy imported brands of batteries, of course, is one of the brands, production performance of hydrogen fuel cells is not bad.

Then I choose to say that the lithium batteries.

In today’s market digital camera, equipped with lithium batteries are some of the major high-end digital cameras. Of course, with increasing popularity of digital cameras, lithium battery for its good performance and will eventually completely replace the hydrogen fuel cell. But now the price of lithium batteries is still relatively expensive, mainly aimed at high end users of digital cameras. Under normal circumstances, if they can afford to buy horses, of course, with affordable saddle.

The use of lithium users of digital cameras, the most direct and simplest is to just buy the store to buy natural pool Yuanzhuanglidian. First, the shop is about not having false, and secondly, the compatibility of pool Yuanzhuanglidian better, there will be no damage to the camera. But having said that, with batteries original equipment Hao Shihao, but it is too expensive. Ordinary pool Yuanzhuanglidian, usually priced at two hundred others, such as “high-priced Sony activists” and Yuanzhuanglidian, priced at 400 yuan or more. Although, as I said before with affordable saddle affordable but there is no way to not spend too much money to achieve similar goals? Answer is obviously yes, or a phrase - “there is a demand, there is the market”, since users need to do it naturally He was thinking of ways for you to solve, but it makes money, but it must benefit, are the so-called double advantage.

In general, the benefits of the battery is relatively high, the lithium batteries is no exception. Thus, the growing demand for lithium batteries, but also continue to attract manufacturers to enter the domestic lithium battery. Like all digital products, domestic manufacturers and foreign manufacturers of the competition the most effective means nothing but “cheap” word. Li-ion batteries currently in production a large number of domestic manufacturers, but rather mixed, although there are many large companies have some level of production, but there is much use of inferior materials, poor workmanship, the benefits of small manufacturers.

So I say, in the following points on how to choose the non Yuanzhuanglidian considerations.

And just said, such as nickel-metal hydride batteries, lithium batteries is still the basic elements of the most important of its batteries. As mentioned above, the first class of batteries lithium batteries are still concentrated in Japan. Some national leaders, which is used batteries in Japan, then mold their own design, parts, so its performance is not inferior to imports of lithium-powered products. While prices are much lower than imported products, generally at 200 yuan. Some small manufacturers, only profits with low-grade production of lithium batteries at a price of 100 yuan, the price so cheap, but not recommended, because it should not be long before the battery fundamental change, not as an investment in place, you can buy at ease. So the first note you want the user when the attention of friends to buy the brand, not to be impressed by the low price, so that “Zhanxiaopianyi facing a significant loss.”

In addition, the user must always be friends before you buy to note is that the camera base used by each of the lithium battery is not the same, so it is best to bring your digital camera to buy, and the field test to ensure that lithium batteries can be purchased from your digital camera from normal use.

Besides the above considerations, the last I mean is that you have purchased lithium batteries after-sales service. As they are not original batteries, lithium batteries are compatible filled with many uncertainties, so we had better do some returned to the commitments undertaken in order to guarantee their rights.

The inherent advantages of Primary Education Drive Adoption Lithium batteries in various applications

Lithium batteries have superior energy density and cycle life compared to other chemistries of the main battery and can last nearly 10 years, making them preferable for critical applications. These batteries have operating temperature and exhibit efficient operation in rugged atmospheres. Increasing industrial automation and automation of the manufacturing sector also supports the need for primary lithium batteries.

“The primary lithium battery market worldwide and generated an estimated $ 1.10 billion in 2007,” explains the analyst of this research. “This market is expected to witness growth medium with lithium / manganese dioxide market growing at a significant rate . However, the market is very competitive among the different chemistries of primary lithium batteries. In addition, the threat of lithium-ion also has influence in the growth of certain primary lithium batteries used in select consumer applications.

Military / defense applications and medical equipment market Encourage Lithium significantly

With increased military reconnaissance operations across the world, the need for sophisticated equipment and technologically advanced has increased several folds. Technical advancements, in turn, lead needs higher energy, which stimulates the demand for batteries for a long term and efficient operation. Primary lithium batteries meet these specifications and increasing military budgets and capital spending directly influences the primary battery market. Lithium batteries are widely used for medical devices in various life support. Many implantable devices, automatic external defibrillators, and infusion pumps prefer primary lithium batteries because they are most suited for medical devices.

One area of concern is that these batteries tend to emit toxic gases and hazardous elements if electrolytes are disclosed. “These batteries cause environmental pollution when disposal is not handled properly,” explains the analyst. “Thus, the manufacture, use and disposal of these batteries involve many regulations to follow, which may affect demand if adequate measures are applied. “
