  • ELECTRICAL POWER STORAGE DEVICES
    Publication number: 20210098795
    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.
    Type: Application
    Filed: October 26, 2020
    Publication date: April 1, 2021
    Inventors: Richard M. Sturgeon, Dennis A. Wetzel, Robert G. Gruenstern, William J. Wruck, Ramachadran Subbarraman, James Symanski, Eberhard Meissner
