Abstract
The application provides a battery cell, a manufacturing method and a manufacturing system therefor, a battery and an electric device. The battery cell in one embodiment of the application includes a casing having an opening and provided with a pressure relief mechanism which is actuated to relieve an internal pressure or temperature of the battery cell when the internal pressure or temperature reaches a threshold value; an electrode assembly accommodated in the casing, and including a body portion and a tab portion protruding therefrom; and a cover assembly for covering the opening. A first recessed portion is formed on one side, abutting against the body portion and facing the electrode assembly, of the cover assembly. The cover assembly is provided with at least one first channel. The first channel can reduce the gas accumulated between the electrode assembly and the cover assembly, thereby reducing the safety risk.
