摘要： Electrochemical cells including a casing or cup for direct electrical contact with a negative electrode or counter electrode and serving as the current collector for the electrode. The casing includes a substrate having a plated coating of an alloy including copper, tin and zinc, the coating having a composition gradient between the substrate and the external surface of the coating wherein the copper content is greater adjacent the substrate than at the external surface of the coating and the tin content is greater at the external surface of the coating than adjacent the substrate. Methods for forming a coated casing and an electrochemical cell including a coated casing are disclosed, preferably including providing an electrode casing with a coating utilizing variable current density plating that reduces discoloration of a surface exposed to the ambient atmosphere.
