Abstract: A pressure relief mechanism includes: a pedestal, a cover assembly, and a position limiter. An exhaust port is provided on the pedestal. The cover assembly is configured to close or open the exhaust port. The position limiter is snap-fastened to the cover assembly. The position limiter includes a first elastomer and a first limiting portion. The first limiting portion is configured to: when the cover assembly closes the exhaust port, restrict the position limiter from moving relative to the pedestal; and when a pressure in the box increases, make the position limiter move along an opening direction of the cover assembly to free the first limiting portion from constraint of the pedestal and enable the position limiter to rotate relative to the cover assembly under resilience of the first elastomer.

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.
