Abstract

The invention provides a cylindrical battery. The cylindrical battery comprises a cylinder, a central tube, a winding cell, a positive electrode cover plate and a negative electrode collector plate. The central tube is arranged in the cylinder, the winding battery core is wound on the central tube, and the positive electrode cover plate comprises a main body and a positive electrode limiting column arranged in the middle of the main body; the main body is connected with the cylinder, at least one part of the positive electrode limiting column is arranged in one end of the central pipe in a penetrating manner, and a liquid injection hole is formed in the positive electrode limiting column; the liquid injection hole is communicated with a cavity in the central tube, and the liquid injection hole and the cylinder are coaxially arranged; the negative electrode collector plate is arranged in the cylinder and comprises a plate body and a negative electrode limiting column arranged in the middle of the plate body, and at least one part of the negative electrode limiting column is arranged in the other end of the central tube in a penetrating manner. By adopting the scheme, the position of the liquid injection hole can be quickly positioned, so that the liquid injection and sealing efficiency is improved; moreover, the positive electrode cover plate and the negative electrode collector plate can be accurately positioned, so that the assembly efficiency is improved, and the assembly quality and the structural reliability are ensured.

Description
