摘要： This invention relates to a method to manufacture cell-cans by DI can method, by manufacturing a bottomed cylindrical cup-shaped intermediate product from a sheet material of which both surfaces are nickel plated and annealed in an atmosphere of inert gas making the metal nickel layer thickness and the hardness at predetermined values, then ironing the intermediate product at a predetermined ironing rate, securing a thickness of the metal nickel layer of more than 1.0 µm and a Vickers hardness of more than HV 200 on the side wall of finished cell-cans. By this, conventional defect problems due to the cracks generated on the intermeiate product can be sovled completely and the problem of hair-lines formed on the surface of finished cell-can can be eliminated.

摘要： A battery has elements for electromotive-force accommodated in a metal outer can (1), the metal outer can (1) being a metal can (4) with a bottom having a cylindrical shape and a bottom thickness (TA)/side thickness (TB) value of 2.5 &tilde& 5.0. The metal outer can (1) consists chiefly of iron and a nickel layer (8) is provided on at least the inner face of the battery. A multiplicity of shallow grooves (7) perpendicular to the bottom face are formed on the surface of the nickel layer (8). In the method, an iron-based metallic sheet formed with a nickel layer (8) on at least one face is subjected to drawing forming into a tubular shape having a bottom. Continuous ironing processing is performed such that the side of the can formed in the tubular shape has an ironing ratio in the range 20 &tilde& 90% and a metal outer can (1) is thereby manufactured having a bottom thickness (TA)/side thickness (TB) value of 2.5 &tilde& 5.0, having a cylindrical shape. A multiplicity of shallow longitudinal grooves are formed in the nickel layer (8) provided on the battery inside face.
