Background

A "lithium battery" is a type of battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a 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 nowadays. 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 lithium metal battery of the rechargeable battery is born in 1996, the safety, specific capacity, self-discharge rate and cost performance ratio of the rechargeable battery are superior to those of the lithium ion battery, but in the use process of the lithium battery, the heat radiation effect between lithium battery packs is poor, the lithium battery is easy to work overheated, and the service life of the lithium battery is shortened, so that the high-safety power lithium battery pack is provided.
