Understanding of the historical development lithium-ion battery industry

Source: 2020 - 04 - This was hits: 14 of the lithium ion battery industry development history since the early 1980 s, China has been developing lithium-ion batteries. In 2000, Japan's annual production of 500 million pieces of lithium ion battery, accounts for over 90% of the global market, China is 35 million pieces. 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 'national medium and long-term science and technology development planning, 2006 - 2020). ', power lithium ion battery is listed as priority development direction of energy efficient materials technology. With national a series of policy support, the lithium ion battery industry in China has made great progress, the lithium battery industry in China has entered the rapid growth stage. Shenzhen byd, shenzhen, tianjin bicycle lichen such as lithium ion battery company rapid rise. In 2004, the lithium ion battery annual output to 800 million, the global market share jumped to 38%, second only to Japan. According to the National Bureau of Statistics, by 2013, China's annual of lithium ion battery is close to 47. 6. 8 billion as the world's main producer of batteries. In the field of space applications, domestic space using circular lithium ion battery more than about 110 ~ 140 Wh/kg. In terms of battery life test on the ground, high orbit satellite at 80% of the defense, hit 15 years life level; Low orbit satellite is 30%, the department of defense has a history of five years the standard of living. In the field of electric vehicles, wanxiang group for shenzhen expo provides electric car lithium-ion batteries and hybrid cars. In addition to continue to work with byd and shenzhen deep cooperation space power research institute, Shanghai automotive industry corporation also cooperate with global lithium secondary battery industry leading technology companies in the United States A123 has set up a joint venture production and sale of car battery system. In the field of grid storage technology, in February 2011, China's first mw battery energy storage battery energy storage power station southern power grid 5 mw power plant in shenzhen successful interconnection. The total capacity of 10 mw battery energy storage power station, after the completion of will become the world's largest lithium ion battery energy storage power station.
