Abstract

The present application is applicable to the technical field of power batteries, and provides a battery cell, a battery, and a power consuming apparatus. The battery cell (100) includes: an adapter (10), where a welding point (20) is formed on the adapter in a protruding manner; and a covering member (30), connected to the adapter and covering the welding point, where an accommodating cavity (40) used to accommodate the welding point is formed between the covering member and the adapter, and at least a portion of the welding point is accommodated in the accommodating cavity. In the battery cell provided in the present application, the accommodating cavity is provided between the covering member and the adapter, and at least a portion of the welding point is accommodated in the accommodating cavity. Accommodating the welding point in the accommodating cavity enables better contact between the covering member and the adapter around the welding point, and reduces the occurrence of suspension of the covering member. Accordingly, a negative impact of the welding point on the covering member is reduced, so that the covering member can be better adhered to the adapter, alleviating the problem of loosening or detaching of the covering member.
