<p>A surface-treated steel sheet for a battery improved in its electric contact with a battery positive electrode active substance, a method of production thereof, a battery case and a battery. The surface-treated steel sheet is formed on at least the surface thereof serving as an inner side of a battery case with a graphite-dispersed nickel-plated layer or a graphite-dispersed nickel-alloy-plated layer, which alloy-plated layer is preferably formed by a nickel-cobalt alloy, nickel-cobalt-iron alloy, nickel-manganese alloy, nickel-phosphorus alloy or nickel-bismuth alloy. The battery case is formed by drawing, DI working and DTR working the above surface-treated steel sheet, and the battery uses the battery case.</p> |
