    Abstract: A battery cell, including a housing, a pressure relief member disposed on a first wall of the housing, an electrode assembly disposed inside the housing, an electrolyte immersing the electrode assembly, and a sealing member and an active substance that are disposed inside the housing. The sealing member is configured to seal the active substance on a side of electrode assembly close to the first wall. The sealing member is configured to be actuated when an internal pressure or temperature of the battery cell reaches a first threshold, to release the active substance, and the active substance is able to react with the electrolyte and/or the electrode assembly to increase the internal pressure or temperature of the battery cell, so as to actuate the pressure relief member. The battery cell can quickly discharge its internal temperature and pressure when experiencing thermal runaway, and the battery cell has good safety performance.
