Abstract

A battery cell (20), a battery (100), and an electric device. The battery cell (20) comprises a casing (210), an electrode assembly (220), electrode terminals (230), and sealing members (240). The casing (210) comprises a first wall (211); through holes (2111) are formed in the first wall (211); the electrode assembly (220) is arranged in the casing (210); the first wall (211) is used for supporting the electrode assembly (220), each electrode terminal (230) is arranged at a corresponding through hole (2111); the electrode terminal (230) comprises a first conductive portion (231); the first conductive portion (231) is arranged on the side of the first wall (211) facing an accommodating space; and each sealing member (240) is arranged between a corresponding electrode terminal (230) and the first wall (211). When the outside of the casing (210) is stressed, the first wall (211) and the electrode terminals (230) can deform together, so that it is not easy to form gaps between the sealing members (240), which are located between the electrode terminals (230) and the first wall (211), and the first wall (211), and between the sealing members (240) and the electrode terminals (230), thereby maintaining good sealing performance between the sealing members (240) and the first wall (211) and between the sealing members (240) and the electrode terminals (230) and reducing the possibility of liquid leakage of the battery cell (20), and thus reducing the possibility of failure of the battery cell (20) and contamination or corrosion of other mechanisms.
