What is the history of lithium batteries in China?

Since the early 1980s, China has been developing lithium-ion batteries. In 2000, Japan's annual output of lithium ion batteries reached 500 million, accounting for more than 900,000 in the global market, while China's annual output was only 35 million. With the development of technology and in order to meet the needs of social development, China has successively issued a series of policies to promote the development of the lithium-ion battery industry: Dynamic lithium-ion batteries are listed as the priority development direction of high-efficiency energy materials technology. With the support of a series of national policies, China's lithium-ion battery industry has made great progress, and China's lithium-ion battery industry has entered a rapid growth stage. Lithium-ion battery companies such as Shenzhen BYD, Shenzhen Bic, and Tianjin Lishen have rapidly emerged. In 2004, China's annual output of lithium-ion batteries reached 800 million, and its global market share soared to 38, second only to Japan. According to the statistics of the National Bureau of Statistics, by 2013, China's annual output of lithium-ion batteries had reached nearly 4.768 billion, and it has become a major global battery manufacturer.

In the field ofspecial applications, the current specific energy of round lithium-ion batteries for space use in China is about 110 to 140 Wh / kg; In the battery ground life test, the high-orbitspecial 80 <UNK> DOD, reached the 15-year life level; The low-orbitspecial 30 <UNK> DOD has reached a five-year life level.

In the field of electric vehicles, Wanxiang Group provided lithium-ion batteries for electric vehicles and hybrid vehicles for the Shanghai World Expo; In addition to continuing deep cooperation with BYD and the Shanghai Institute of Space Power, Shanghai Automobile has also formed a joint venture with the United States A123, which is the leading technology in the global lithium secondary battery field, to produce and sell automotive power battery systems.

In the field of grid energy storage technology, in February 2011, China's first megawatt battery storage power station, the South Grid 5MW battery storage power station, was successfully connected in Shenzhen. The total capacity of the battery storage power station is 10 MW. After it is fully put into operation, it will become the world's largest lithium-ion battery storage power station.
