BATTERY CELL, BATTERY, AND POWER CONSUMING DEVICE

Provided are a battery cell, a battery, and a power-consuming device. The battery cell includes a housing, an electrode assembly, and an insulator. The electrode assembly is accommodated within the housing and is formed by winding and/or stacking electrode plates. The electrode assembly has a first end surface, and the insulator is at least partially disposed between the first end surface and the housing. A portion of the insulator opposite the first end surface is provided with at least one first through hole, where the first through hole is strip-shaped. A length direction of the first through hole is parallel to or inclined relative to a stacking direction of electrode plates exposed by the first through hole. According to the technical solutions of the present application, battery yield can be improved, thereby reducing production costs.
