Description
Technical Field

[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. 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 product of rechargeable batteries, the lithium metal battery, was born in 1996. Its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to those of lithium-ion batteries. Due to its own high-tech requirements, only companies in a few countries produce this type of lithium metal battery. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. As lithium batteries are used more and more, waterproofing of lithium battery cells becomes increasingly important, but there are still many defects.
[0003] The following problems exist in the prior art:
[0004] 1. For the waterproof device for lithium battery cells in the prior art, the waterproof effect is poor.

[0005] 2. For the waterproof device for lithium battery cells in the prior art, the functionality is low. For the waterproof devices for lithium battery cells on the current market, most only have the function of waterproofing. When waterproofing the lithium battery cells, the lithium battery cells cannot be used, and manual disassembly is often required, wasting time and manpower. Moreover, multiple disassembly operations will damage the device and reduce its waterproof ability, and the feasibility is low. Content of the Utility Model
