Abstract: A battery including a curved metal shell, a curved metal plate, and a curved electrode assembly. The curved metal shell has a curved surface and a plurality of side walls extending from the curved surface. The curved electrode assembly is disposed between the curved metal shell and the curved metal plate. The plurality of side walls are bound with the curved metal plate to seal the curved electrode assembly between the curved metal shell and the curved metal plate. By disposing a direction of an opening of the curved metal shell, the difficulty in the manufacturing process of the battery is greatly reduced, curved electrode assemblies in different structural forms are placed into the curved metal shell more conveniently and smoothly, and the energy density of the battery is also increased.
