Sealing device for sealing lithium battery cap and implementation method thereof
Technical Field
The invention relates to the technical field of sealing, processing and sealing of lithium battery caps, in particular to a sealing, processing and sealing device of a lithium battery cap and an implementation method thereof.
Background
A "lithium battery" is a type of battery using a nonaqueous electrolyte solution with 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 the safety, specific capacity, self-discharge rate and cost performance of rechargeable batteries 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.
