"Lithium Battery" is a kind of battery which is made of lithium metal or lithium alloy as anode material and uses non hydro solution. 1912 Lithium Metal Battery was first proposed and studied by Gilbert N Lewis. In the 1970s, M. Whittingham proposed and began studying lithium-ion batteries. Because the chemical properties of lithium metal are very lively, the processing, preservation and use of lithium metal are very high in environmental requirements. Therefore, lithium batteries have not been used for a long time.With the development of science and technology, lithium battery has become the mainstream now.
