A steel sheet for a battery container is covered with nickel-tin alloy layer on one side to be the inner side of the battery container which is formed by drawing the steel sheet. A battery using the steel sheet is manufactured by firstly filling positive electrode mix consisting of manganese oxide, graphite and potassium hydroxide and secondly filling negative electrode active material consisting of zinc and potassium hydroxide in the battery container.

Surface treated steel sheet for battery containers, a battery container,

A coated metal sheet for use in a battery container is made up of a metal sheet, one side of which is coated with a coating that includes a resin having rubber elasticity, a plasticizer, a crosslinking agent, and a conductive powder. A battery container or battery is produced from such a coated metal sheet.

A method for producing a thin tin and nickel plated steel sheet having a surface structure in which the distribution of numerous nodules of metallic tin are observed by using an electron microscope on an iron-tin-nickel alloy layer formed on a steel sheet which comprises electroplating nickel on the steel sheet which is anodically treated in an alkaline electrolyte with a pH of above 10 followed by electrotinplating the nickel plated steel sheet, reflowing, quenching, and then chromate treating the tin and nickel plated steel sheet. This tin and nickel plated steel sheet is suitable for welded can materials since it is excellent in corrosion resistance after lacquering and weldability.
