  • Patent number: 10665825
    Abstract: 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 ?m or more.

  • Patent number: 10030283
    Abstract: Provided is a method for producing a surface-treated steel sheet for battery containers including: a first process of forming an iron-nickel alloy plating layer on at least one side of a steel sheet; a second process of forming a nickel plating layer on the iron-nickel alloy plating layer; and a third process of performing a thermal treatment after forming the nickel plating layer to form an iron-nickel alloy layer having an outermost surface, at which a content ratio of Fe atoms is 12 to 55% by atom, on an outermost layer by thermal diffusion. The invention makes it possible to provide the method for producing the surface-treated steel sheet for battery containers that can suppress the elution of iron inside the battery when being used for a battery container, whereby the service life of the battery can be extended and battery characteristics such as discharge characteristics can be improved.

  • Patent number: 9017862
    Abstract: 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 CuK? 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 2? within a range of 41° or more and less than 43° to an intensity IB of a peak present at a diffraction angle 2? within a range of 43° or more and 45° or less.
