Abstract

The invention relates to a battery monomer, a battery, an electric device, a manufacturing method and manufacturing equipment. The battery monomer includes: a shell having a wall portion; and a pressure relief mechanism which is arranged on the wall part and comprises a main body part and a weak part connected to the main body part, wherein the main body part is used for being connected with the wall part, and the pressure relief mechanism is used for damaging the weak part to relieve pressure when the internal pressure or temperature of the battery monomer single battery reaches a threshold value, the pressure relief mechanism further comprises a reinforcing part arranged on the main body part in the thickness direction of the main body part, the reinforcing part is used for reducing deformation of the main body part, and the reinforcing part protrudes out of the surface of the main body part in the thickness direction. The battery monomer provided by the invention aims to solve the problem of explosion pressure relief when the single monomer is not subjected to thermal runaway.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a battery cell, a battery, an electrical device, a manufacturing method, and a manufacturing device. 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 present application provides a battery cell, a battery, an electrical device, a manufacturing method, and a manufacturing device, aiming to solve the problem of explosion and pressure release of the battery cell when thermal runa...
