  • Patent number: 11575119
    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.
    Type: Grant
    Filed: February 4, 2021
    Date of Patent: February 7, 2023
    Assignee: TROJAN BATTERY COMPANY, LLC
    Inventors: Cormac O'Keeffe, Marvin Ho
  • Patent number: 11233275
    Abstract: An electrospun coated component for a lead acid battery is disclosed. The electrospun coated component includes positive electrode, negative electrode, and separator. The separator may comprise a low-conducting and/or non-conductive material. A method of electrospun coating these components of a LAB is provided. Suitable compositions and conditions for electrospun coating on to LAB components are further provided in this disclosure.

  • Publication number: 20210320300
    Abstract: 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.
