Abstract

The present application discloses a battery cell, a battery, and an electrical device. The battery cell comprises a casing, an electrode terminal, an electrode assembly, and a first insulating member. The casing has a first wall and a second wall, and the second wall surrounds the edge of the first wall. The electrode terminal is mounted on the first wall in an insulating manner. The electrode assembly is accommodated in the casing. The electrode assembly comprises a main body portion, a first tab and a second tab, and the first tab and the second tab have opposite polarities. In a thickness direction of the first wall, the main body portion has a first end surface close to the first wall, and the first tab and the second tab are both provided on the first end surface. The first tab is electrically connected to the electrode terminal, and the second tab is electrically connected to the casing. The first insulating member is provided on the outer peripheral surface of the main body portion, and a portion of the first insulating member is located between the first tab and the second wall, so that the first tab and the second wall are insulated and isolated from each other. The technical solution provided in the present application can improve the reliability of the battery.
