Abstract: Provided are a battery cell, a battery, and an electrical apparatus. The battery cell includes a case, an electrode assembly, a first electrode terminal, and a cover plate. The case includes a cylinder and a cover body that are integrally formed, and the cylinder has an opening at the end facing away from the cover body. The electrode assembly is accommodated in the case and includes a first tab. The first electrode terminal is arranged on the cover body and is configured for electrical connection with the first tab. The cover plate is connected to the cylinder and covers the opening. The first electrode terminal is mounted to the cover body, which can increase a distance between a joint between the cylinder and the cover plate and the first electrode terminal.
