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.
