With the development of micro electronics technology in twentieth Century, the miniaturization of the equipment is increasing, and the power of the power raised a high demand. The lithium battery has entered a large practical stage..

Lithium ion batteries are widely used in mobile phones, laptops, electric vehicles, electric vehicles, street lamps standby power, air lights, household appliances, can be said to be the largest application groups.

With the rapid development of China's mobile phone, notebook computers, digital cameras, electric cars, electric tools, new energy vehicles and other industries, growing demand for lithium batteries will be. At the same time, due to lithium battery manufacturers in technology innovation, people's demand of lithium batteries will still growing, is expected to 2012 of lithium battery production growth will remain above 10%, is expected by 2015 China lithium battery industry output value will reach 35.3 billion yuan. Especially the use of lithium batteries is becoming a core technology in the automobile field, and the development prospect is immeasurable.
