  • 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.
    Type: Application
