Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are all superior to lithium-ion batteries. Due to their own high technical requirements, only companies in a few countries are producing such lithium metal batteries. When coating lithium batteries, a coating and drying device is required.
