Background

A lithium battery is a type of battery using a nonaqueous electrolyte solution, using lithium metal or a lithium alloy as a positive/negative electrode material. Lithium metal batteries were first proposed and studied by Gilbert n.lewis in 1912. In the 70 s of the 20 th century, m.s.whitetingham proposed and began to study lithium ion batteries. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. With the development of science and technology, lithium batteries have become the mainstream; lithium batteries can be broadly classified into two types: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium in the metallic state and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and their safety, specific capacity, self-discharge rate and cost-performance ratio were all superior to those of lithium ion batteries. Because of the limitation of high technical requirements of the lithium metal battery, only a few national companies produce the lithium metal battery, and the utility model relates to a combined small lithium battery;
