  • Publication number: 20240128467
    Abstract: An electrical storage device includes high surface area fibers (e.g., shaped fibers and/or microfibers) coated with carbon (graphite, expanded graphite, activated carbon, carbon black, carbon nanofibers, CNT, or graphite coated CNT), electrolyte, and/or electrode active material (e.g., lead oxide) in electrodes. The electrodes are used to form electrical storage devices such as electrochemical batteries, electrochemical double layer capacitors, and asymmetrical capacitors.

  • Patent number: 10205157
    Abstract: An electrode for a lead acid battery is provided. The electrode includes a pasting material distributed on the electrode and arranged to provide uniform current density. A lead acid battery having a plurality of electrodes, each electrode having pasting material providing uniform current density across the electrodes is also provided. A method for manufacturing a battery electrode is also provided and includes applying a portion of the electrode with a pasting material providing uniform current density.

  • Patent number: 10044043
    Abstract: A battery electrode with a pasting textile, fabric, or scrim made with an electrode grid (e.g., a stamped grid or expanded metal grid) coated in battery electrode and covered with pasting textile formed of a bonded, non-woven fiber web. The web is formed from one or more fibers with an average length greater than 20 ?m. In various embodiments, the web is formed from one or more spun, continuous fibers. The battery electrode may be made in a continuous process where multiple grids are formed in a single sheet, coated with electrode active material and the scrim before being cut into individual electrodes.
