Document Type and Number:
WIPO Patent Application WO/2023/168669
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries, in particular to a battery cell, a battery, an electric device, and a manufacturing method and apparatus for a battery cell. The battery cell comprises: a casing, comprising a first wall; electrode terminals, arranged on the first wall and used for outputting or inputting electric energy; and a pressure relief mechanism, arranged on the first wall and used for being actuated to relieve internal pressure when the internal pressure or temperature of the battery cell reaches a threshold value, wherein the first wall comprises a first part and a second part, the first part comprises a first surface away from the interior of the battery cell, the second part is sunken in a direction toward the interior of the battery cell relative to the first surface, and the electrode terminals and the pressure relief mechanism are arranged on the second part. The pressure relief mechanism and the electrode terminals of the battery cell provided by the present application are less likely to be damaged by impact, and the service life of the battery cell is long.
