Abstract

The present application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes: a housing, the housing including a first surface, a second surface, a third surface, and a flange, where the flange is disposed around the first surface and connected to the first surface, the first surface and the third surface are opposite each other, and the second surface is connected between the flange and the third surface; and an insulating film, wrapped around an exterior of the housing, the insulating film wrapping around at least a portion of the first surface, at least a portion of the flange, at least a portion of the third surface, and at least a portion of the second surface. The insulating film is folded from the flange to the second surface to form a first folded region, and the insulating film is folded from the third surface to the second surface to form a second folded region. Along a direction from the first surface to the third surface, a dimension of the first folded region is smaller than a dimension of the second folded region. The insulating film is also capable of sufficiently wrapping around the housing when the housing is provided with a flange.
