Abstract
A lead oxide for use in making an active material for pasted lead-acid battery plates comprises a doped lead oxide, the dopant preferably being copper in an amount of about 0.01 to about 0.07 percent based upon the total weight of the lead oxide. The use of such a doped oxide imparts to the resulting battery improvement in various of the electrical performance characteristics such as, for example, internal resistance, capacity, cycle life and the like.
