Title:
BATTERY CELL, BATTERY, ENERGY STORAGE APPARATUS, AND ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/082096
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries, and provides a battery cell, a battery, an energy storage apparatus, and an electrical apparatus. The battery cell comprises a housing and a pressure relief member. The housing has a first wall, and the first wall has a first side surface facing the interior of the battery cell. The pressure relief member is disposed on the first wall. The pressure relief member has a weak structure. The pressure relief member is configured to relieve the internal pressure of the battery cell. In the thickness direction of the first wall, the weak structure does not go beyond the first side surface in a direction toward the interior of the battery cell. The structure can well protect the weak structure of the pressure relief member, to prevent abrasion or damage to the weak structure of the pressure relief member caused when the weak structure projects out of the first side surface during assembly or stacking storage of the battery cell, so as to prolong the service life of the pressure relief member and improve use reliability of the pressure relief member, thereby ensuring normal use of the pressure relief member, and lowering the risk of early functioning of the pressure relief member.
