Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. In 1912, lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, MS Whittingham proposed and Lithium-ion batteries have been studied. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. With the development of science and technology, lithium batteries have become the mainstream.
