Abstract
A binary lead-tin alloy substrate for support of the electrochemically active material in lead-acid cells is disclosed having a tin concentration from about 0.3 to about 0.9 weight percent, the balance being lead. The tin impedes the formation of a passivation layer at the interface between the grid material and the active material improving cell recovery from deep discharge and improving cold cranking amperes performance.
