PLATED STEEL PLATE FOR BATTERY CAN, BATTERY, AND ALKALINE DRY BATTERY

摘要

This invention provides a plated steel plate for a battery can, which can impart stable and good electric contact to the outer surface of a battery can, can reduce damage to a plated surface in the preparation of a battery can by draw pressing and thus can suppress the evolution of gas within the battery. The above construction can realize a battery and an alkaline dry battery that can realize a stable electric contact state with instruments and evolves no significant amount of gas. In a plated steel plate (110) for a battery can having both sides plated mainly with nickel, one side of the steel plate (111) as the substrate for the plating is a dull finished face (111a) while the other side is a bright finished face (111b).
