"Lithium battery", is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution. Lithium battery as early as 1912 by Gilbert n. Lewis and study are put forward. In the 1970 S, M. S. Whittingham is put forward and began to research on lithium ion batteries. Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment. So, the lithium battery has not been applied for a long time. With the development of science and technology, the lithium battery has now become the mainstream. Lithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries. Lithium ion battery does not contain lithium metal state, and can be recharged. The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries. Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.
