Abstract
Disclosed are electrode plates for a lead acid battery. The electrode plates are formed of an electrode plate having a face, the electrode plate comprising a lead or lead alloy grid coated with an active material and the electrode plates having a porous, non-woven mat comprised of polymer fibers coating on the face of the electrode plate, as well as a method for making the coated electrode plates and lead acid batteries containing the coated electrode plates.
