Abstract: A battery cell includes an electrode assembly and a first tab. The electrode assembly includes a separator. An outer surface of the electrode assembly includes a first lateral face and a second lateral face disposed opposite to each other along a first direction, and a first end face and a second end face disposed opposite to each other along a second direction. One end of the first tab is electrically connected to the first electrode plate, and another end of the first tab extends out from the first end face. The first tab includes a first surface and a second surface. The first surface is oriented toward the first lateral face, and the second surface is oriented away from the first lateral face. The first end face includes a first region. The first region is located between the first surface and the first lateral face.
