摘要： Disclosed is a lead acid battery having a negative electrode plate and a positive electrode plate, each plate formed of a lead-antimony grid coated with an active material. A separator is disposed between the first and second electrode plate faces and an electrolyte solution immersing the negative electrode plate, the positive electrode plate the separator. At least one of the lead-antimony electrode grids, the separator or the electrolyte solution contains TiO2, an amount sufficient to suppress the migration of antimony from the positive electrode plate to the negative electrode plate.

摘要： 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.
