Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the positive and negative electrode materials and a non-aqueous electrolyte solution. Gilbert N. Lewis first proposed and researched lithium metal batteries in 1912. In the 1970s, M. S. Whittingham proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use place high demands on the environment. With the advancement of science and technology, lithium batteries have become mainstream.
