What is the history of lithium battery in China?

China began to carry out research and development of lithium ion batteries in the early 1980s. In 2000, Japan produced 500 million lithium-ion batteries annually, accounting for more than 90 percent of the global market. With the development of technology, in order to meet the needs of social development, China has issued a series of policies to promote the development of lithium ion battery industry: in the outline of national medium and long term scientific and technological development plan (2006-2020), dynamic lithium ion battery is listed as the priority development direction of high-efficiency energy material technology. Supported by a series of national policies, China's lithium ion battery industry has made great progress, and China's lithium battery industry has entered a stage of rapid growth. 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 data of the national bureau of statistics, by 2013, China's annual output of lithium ion batteries has reached nearly 4.768 billion, which has developed into a global battery manufacturing country.

In the field ofspecial applications, the specific energy of circular lithium ion batteries used in domestic space is about 110 ~ 140Wh/kg. In terms of battery ground life tests, 80% of DOD's high-orbitspecials have achieved the 15-year life level. Thirty percent of DOD's low-orbitspecials now have a five-year lifetime.

In the field of electric vehicles, wanxiang group provided lithium ion batteries for electric and hybrid vehicles for the Shanghai world expo. In addition to continuing in-depth cooperation with byd and Shanghai space power research institute, saic has also established a joint venture with A123, the world's leading technology company in the field of lithium secondary batteries, to produce and sell vehicle power battery systems.

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