BATTERY CELL, BATTERY AND ELECTRIC DEVICE

Abstract: a battery cell, a battery, and an electric device are described. the battery cell includes a casing and a first insulating member. the casing is provided with a pressure relief mechanism. the first insulating member wraps the outer surface of the casing, the first insulating member has a first overlapping region, and the first overlapping region does not overlap with the pressure relief mechanism. in this way, the first overlapping region of the first insulating member does not block the pressure relief mechanism, reducing the risk of the pressure relief mechanism failing to release pressure in time due to that the first overlapping region of the first insulating member blocks the pressure relief mechanism, thereby improving the timeliness of pressure relief of the pressure relief mechanism and improving the reliability of the battery cell.
