摘要： A battery shell includes a first housing. The first housing is configured to be formed by winding a sheet around a first axis. The sheet includes a first end portion and a second end portion. The first housing includes a first sidewall. The first sidewall includes a first flat portion, a first bent portion, and the first end portion. The first sidewall further includes a second flat portion and the second end portion. A wall face of the first flat portion facing away from the first axis is a first wall face. A wall face of the second flat portion facing away from the first axis is a second wall face. As viewed along a thickness direction perpendicular to the second flat portion, a distance between the first wall face and the second wall face is less than a thickness of the second flat portion.
