Title:
BATTERY CELL, BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/245429
Kind Code:
A1
Abstract:
Provided in the present application are a battery cell, a battery and an electric device. The battery cell comprises a shell comprising a first wall; an electrode assembly arranged in the shell; an electric energy leading-out part arranged in the shell and connected to the electrode assembly; a pressure relief mechanism arranged on the first wall; and a supporting member, which is arranged in the shell and configured to be able to restrain the electric energy leading-out part from shielding a pressure relief hole formed in the pressure relief mechanism when the battery cell is subjected to thermal runaway. The supporting member in the technical solution of the present application can avoid the problem of unsmooth air exhaust and pressure relief of the battery cell due to the electric energy leading-out part shielding the pressure relief hole formed in the pressure relief mechanism when the battery cell is subjected to thermal runaway, thus reducing the risks of fire outbreak and explosion caused by unsmooth pressure relief of the battery cell during thermal runaway, and effectively improving the safety performance of the battery cell.
