Abstract
Surface treated steel sheets for battery containers according to the present invention are composed of two surfaces, one of which is to be used as an inner surface of a battery container and the other as an outer surface of a battery container. On the inner surface, between the topmost nickel-tin alloy layer and the base steel sheet are formed intermediate layer(s) of nickel-iron, or nickel and nickel-iron, or nickel-tin-iron and nickel-iron. The present invention also relates to battery containers and batteries made from these surface treated steel sheets.
