Abstract

The invention discloses a columnar battery or button battery. The battery consists of a cover, a shell and a seal ring, both the cover and the shell are a cylindrical structure with a lid part, and the cover and the shell are buckled together to form an enclosed space for accommodating a battery core, the seal ring is located between a side wall of the cover and a side wall of the shell, and can shrink or be torn at a set temperature so as to form a slit between the side wall of the cover and the side wall of the shell for pressure relief. The seal ring of the battery can shrink or be torn ata set temperature to relieve pressure. Therefore the battery provided by the invention has the characteristic of excellent safety performance.

Description

technical field [0001] The present invention relates to the technical field of batteries, and more specifically, to a cylindrical battery or a button battery. Background technique [0002] Cylindrical cells or button cells typically consist of a cover, case and cells. The cover and the casing are snapped together to form a closed space inside them. The cover and the shell are made of metal materials, such as stainless steel. The cells are located in a confined space. The positive pole lug of the cell is connected to the cover, and the negative pole lug is connected to the casing. The cover serves as the positive pole of the battery, and the case serves as the negative pole of the battery. There is a sealing ring between the positive pole and the negative pole. The sealing ring seals the cover and the housing and insulates them from each other. [0003] In the event of a short circuit, overcharge, overload, or external heating of the battery, the temperature inside the ...
