Abstract

The application relates to a battery cell, a battery, an electrical device, a method and equipment for preparing a battery cell, the battery cell includes: a casing, the casing has a wall; a pressure relief mechanism, the pressure relief mechanism is arranged on the wall, and The pressure mechanism includes a weakened part and a first part and a second part arranged on both sides of the weakened part, the weakened part is used to connect the first part and the second part, and the pressure relief mechanism is configured so that the weakened part is destroyed when the pressure inside the casing reaches a threshold value to release the pressure; the protective component, the protective component is arranged on the pressure relief mechanism, and the protective component is used to connect the first part and the second part, so as to increase the connection strength between the first part and the second part. The battery cell, battery, electrical device, method and equipment for preparing the battery cell provided by the application aim to solve the problem of explosion and pressure release of the battery cell when thermal runaway does not occur.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a battery cell, a battery, an electrical device, a method and equipment for preparing a battery cell. Background technique [0002] Due to the advantages of high energy density, high power density, high cycle times and long storage time, rechargeable batteries have been widely used in electric vehicles, mobile devices or power tools. A battery includes a plurality of battery cells connected in series, parallel or in parallel. During the use of the battery, when the battery cell does not experience thermal runaway, there may be explosion and pressure release, which affects the normal use of the battery. Contents of the invention [0003] The application provides a battery cell, a battery, an electrical device, a method and equipment for preparing the battery cell, aiming at solving the problem of explosion and pressure release of the battery cell when thermal runaway...
