Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery packs, and in particular to a lithium battery pack structure with a waterproof function. Background Art

[0002] Lithium battery packs are a commonly used type of energy storage battery. When in use, people often move them outdoors and use them to power some equipment placed outdoors. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. 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 better than lithium-ion batteries; due to their own high technical requirements, only companies in a few countries are producing such lithium metal batteries.

[0003] Most of the existing lithium battery packs are not equipped with waterproof mechanisms when they are stored, so they do not have waterproof functions. When encountering rainy weather, personnel need to move the lithium battery pack to a place without rain to prevent rainwater from entering the lithium battery pack. It is laborious to move the lithium battery pack, which is inconvenient for personnel to place it outdoors for use and difficult to protect safely. Therefore, it is necessary to design a corresponding technical solution to solve this problem. Summary of the invention
