BATTERY CELL, BATTERY, AND ELECTRIC APPARATUS

The present application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes a housing, an electrode terminal, and an insulating member. The housing has a first wall, where the first wall has a first through hole. The electrode terminal is disposed in the first through hole, and along a first direction, the electrode terminal has a first end, where the first direction is parallel to a thickness direction of the first wall. At least a portion of the insulating member is disposed between the electrode terminal and a wall of the first through hole, and the insulating member connects the electrode terminal and the first wall. Along the first direction, a projection of the first end does not overlap with a projection of the insulating member. The technical solutions provided by the present application can improve the reliability of the battery.
