Abstract
An electrode for a lead-acid battery comprising a current collector and active material carried by said current collector wherein the active material includes a conductive filler or a mixture of conductive and non-conductive fillers such that the utilization of active material is greater than 35% at the one hour rate. In addition, the active material may form multilayers wherein the several layers of the multilayers may contain varying amounts of fillers either conductive or non-conductive.
