The utility model belongs to the technical field of new energy batteries, and provides a battery shell which comprises a frame body and a bottom plate, one part of the frame body is bent to form a frame, one side of the frame is in an opening state, and the bottom plate is inserted into the bottom of the frame in the bent state from the opening. And the rest part of the frame body is bent and encloses and seals the bottom plate in the bottom of the frame. The utility model has the advantages of integral aluminum extrusion box body structure, simple structure, light weight, low cost, frame integral bending structure design, simple structure, fewer parts, low cost, rigid physical support of the bottom plate, high structural strength, smaller product deformation and high reliability, and the bottom plate is inserted into the groove connecting structure extruded by the frame to realize rigid physical support. The method is different from a traditional method that no rigid support exists and connection is achieved
