  "textContent": "The battery cell includes a housing, a pressure relief mechanism, and a reinforcement member. The housing has a wall portion, where the wall portion has an inner surface facing an interior of the housing, and the inner surface is provided with a groove. The pressure relief mechanism is disposed on the wall portion. The reinforcement member is at least partially accommodated in the groove, and the reinforcement member is disposed around the pressure relief mechanism. Since the reinforcement member is accommodated in the groove, a height by which the reinforcement member protrudes from the wall portion can be reduced. Accommodating at least a portion of the reinforcement member in the groove can enhance rigidity and strength at a position where the groove is provided, improving strength and rigidity of the wall portion without significantly increasing the weight of the wall portion.",
