Novel impact-resistant lithium battery

Technical Field

The utility model relates to a lithium cell technical field specifically is a novel lithium cell shocks resistance.

Background

Lithium batteries are batteries using a nonaqueous electrolyte solution and using lithium metal or a lithium alloy as a negative electrode material. 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. Therefore, lithium batteries have not been used for a long time. 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 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 national companies are producing such lithium metal batteries today.
