Description

Technical Field

[0001] The utility model belongs to the technical field of lithium batteries, and in particular relates to a small lithium battery which is easy to disassemble and assemble. Background Art

[0002] 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 highly 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.

[0003] 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 superior to lithium ion batteries.

[0004] Some devices only use cylindrical small lithium batteries that need to be connected to each other to power the device. However, when the small lithium batteries are damaged, all small lithium batteries need to be removed to replace the damaged small lithium batteries located inside, resulting in cumbersome operations every time the damaged small lithium batteries are replaced.
