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.
Claims67
An electrode plate for a lead acid battery having a coating comprising:
- an electrode plate for a lead acid battery comprising a lead or lead alloy grid coated with an active material and
- a porous, non-woven mat comprised of polymer fibers arranged with the electrode plate.
A method for coating an electrode plate for a lead acid battery comprising the step of:
- electrospinning a polymer onto the surface of an electrode plate collector, the electrode plate collector comprising a lead or lead alloy grid coated with an active material, to form a porous, non-woven mat coating comprised of polymer fibers on the surface of the electrode plate collector.
A lead acid battery comprising:
- a housing containing
- a negative electrode plate;
- a positive electrode plate, where the electrode plates are comprised of a lead or lead alloy grid coated with an active material;
- a separator disposed between the first and second electrode plates;
- an electrolyte immersing the negative electrode plate, the positive electrode plate the separator;
- a porous, non-woven mat comprised of polymer fiber arranged with one of the electrode plates.
