摘要： A surface-treated steel sheet for battery cases is provided which comprises a nickel-cobalt alloy layer formed at the outermost surface of a plane to be an inner surface of a battery case. When X-ray diffraction measurement using CuKα as a radiation source is performed for the nickel-cobalt alloy layer, an intensity ratio IA/IB=0.01 to 0.9. The intensity ratio IA/IB is a ratio of an intensity IA of a peak present at a diffraction angle 2θ within a range of 41° or more and less than 43° to an intensity IB of a peak present at a diffraction angle 2θ within a range of 43° or more and 45° or less.

摘要： A surface-treated steel sheet for battery containers is provided. The surface-treated sheet is used to form a battery container for a battery. The battery uses a nonaqueous electrolytic solution as an electrolytic solution. The surface-treated steel sheet includes a base material made of steel and an iron-nickel diffusion layer formed by performing thermal diffusion treatment after forming a nickel plating layer at least on a surface of the base material to be located at the inner surface side of the battery container. The iron-nickel diffusion layer has an outermost layer of which a ratio of Ni and Fe is 7.5 or less as a molar ratio of Ni/Fe. The iron-nickel diffusion layer has a thickness of 0.6 μm or more.
