  • Publication number: 20230395881
    Abstract: A thermal runaway trigger method relates to the technical field of batteries. The thermal runaway trigger method includes: providing a battery cell and a heating member arranged in the battery cell; and heating the inside of the battery cell by the heating member, so as to cause a thermal runaway of the battery cell. The heating member is arranged inside the battery cell, and the heating member heats the inside of the battery cell to cause the thermal runaway of the battery cell, so that the inside of the battery cell can be heated to cause the thermal runaway of the battery cell in a relatively short time. Due to the reduced internal space of the battery cell, the range of diffusion of the heating member inside the battery cell is small, and the heat loss of the heating member is relatively small.

  • Publication number: 20220416360
    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.
