NI-PLATED METAL SHEET, WELDED STRUCTURE, AND METHOD FOR MAKING BATTERY MATERIAL

摘要

[Problem] To provide an Ni-plated metal sheet having excellent welding properties, a welded structure, and a method for making a battery material. [Solution] An Ni-plated metal sheet (2) obtained by forming a first Ni-plating layer on the surface of a substrate (2b) formed of a metal sheet, and forming a second Ni-plating layer thereon. The thickness of the second Ni-plating layer is 0.50 µm or more, and the total average concentration of C and S from the surface of the second Ni-plating layer to a depth of 0.4 µm is 1.0 mass% or less.
