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.whittingham 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 scientific 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. Due to its own high technical requirement limits, only a few countries of companies are producing such lithium metal batteries.

The existing lithium battery, particularly the shell part of the lithium battery needs to be dried and dehumidified. However, the existing drying and dehumidifying equipment generally dries and dehumidifies the battery shell through the airflow generated by the hot air blower, and this method has defects, for example, the hot air blower is not easy to dehumidify multiple positions of the battery, which is not beneficial to uniform drying and dehumidifying of the battery; and hot air is blown on the lithium battery, so that heat loss is fast, heat generated by an air heater is not reasonably and effectively utilized, and defects exist.
