NOVELTY - The utility model claims a steel shell for alkaline zinc-manganese battery, claims a directly converting technical field of chemical energy into electric energy. the shell comprises one end open and the other end closed cylinder arranged on the cylinder closed end of anode head and set on the open end of the cylinder body and the cylinder body is an integrated structure. the diameter of the inner wall of the sealing part equal to the diameter of the inner wall of the cylinder body, and the wall thickness of the sealing part is more than the wall thickness of the cylinder body, the outer surface of the tube body is set with metal net layer, metal net layer of the cylinder body of the outer diameter is less than the outer diameter of the sealing part is fixed; the inner wall of the cylinder body is coated with graphene conductive layer. the steel shell relative to the prior art without increasing the manufacturing material while keeping the whole intensity of the cylinder body and effectively improves the electron conductivity of the conductive coating, reduces the axial resistance of the associated conductive coating.
