Abstract

The present application discloses a battery cell (12), a battery (100), and an electric device, pertaining to the field of battery technology. The battery cell (12) includes a housing (121), an electrode terminal (123), and a fixing member (125). The housing (121) includes a first wall (128), and the first wall (128) is provided with a first through hole (1281). The electrode terminal (123) includes a main body (1231) and a step portion (1232), where at least a portion of the main body (1231) passes through the first through hole (1281), the step portion (1232) and the main body (1231) are integrally formed, the step portion (1232) protrudes from a peripheral surface of the main body (1231), and the step portion (1232) is located on an outer side of the first wall (128). The fixing member (125) is made of a metal material. The fixing member (125) is provided with a second through hole (1251) for the main body (1231) to pass through. In a thickness direction of the first wall (128), at least a portion of the fixing member (125) is located between the first wall (128) and the step portion (1232) and abuts against the step portion (1232). In the thickness direction of the first wall (128), the main body (1231) has a first end surface facing away from an interior of the housing (121), the fixing member (125) has a second end surface facing away from the first wall (128), and the first end surface extends beyond the second end surface. The energy density of the battery (100) is increased.
