Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A lead-acid battery comprising: a positive electrode, a negative electrode, and a separator between the positive electrode and the negative electrode; the positive electrode, negative electrode, and separator contained within a housing having electrolyte; and a porous conductive additive comprising fibers having a conductive core comprised of a first material and a surface formed of a second material with the second material comprising one or more materials selected from the group of graphite, expanded graphite, activated carbon, carbon black, carbon nano fibers, and CNT, wherein the fibers have a cross sectional diameter ranging from about 1 micron to about 100 microns, and wherein the fibers are configured to help optimize charge acceptance. 2. The battery of claim 1 , wherein the second material comprises graphite. 3. The battery of claim 1 , wherein the second material is expanded graphite. 4. The battery of claim 1 , wherein the porous conductive additive is provided in electrode active material. 5. The lead-acid battery of claim 4 , wherein the porous conductive additive is provided in negative electrode active material. 6. The battery of claim 1 , wherein the fibers are configured to help optimize charge acceptance.
