Abstract
Official abstract text for this publication.
A graphite-containing electrode includes a porous body that has a plurality of first graphite-containing elements and a plurality of second graphite-containing elements intermingled with the first graphite-containing elements. The first graphite-containing elements have a first degree of graphitization and the second graphite-containing elements have a second, different degree of graphitization.
First claim
Opening claim text (preview).
What is claimed is: 1. A graphite-containing electrode comprising: a porous body including a plurality of first graphite-containing elements and a plurality of second graphite-containing elements intermingled with the plurality of first graphite-containing elements, the plurality of first graphite-containing elements having a first degree of graphitization and the plurality of second graphite-containing elements having a second, different degree of graphitization, wherein the first degree of graphitization differs from the second degree of graphitization by 25%, wherein the degree of graphitization is an amount of graphite in the graphite-containing elements, wherein one of the plurality of first graphite-containing elements and the plurality of second graphite-containing elements include portions that are amorphous carbon. 2. The graphite-containing electrode as recited in claim 1 , wherein the plurality of first graphite-containing elements and the plurality of second graphite-containing elements are fibers. 3. The graphite-containing electrode as recited in claim 2 , wherein the fibers have a length, and a uniform diameter along the length, and the fibers are elongated with regard to the diameter. 4. The graphite-containing electrode as recited in claim 1 , wherein the plurality of first graphite-containing elements are non-fiber particles and the plurality of second graphite-containing elements are fibers. 5. The graphite-containing electrode as recited in claim 4 , wherein the non-fiber particles have a non-uniform diameter. 6. The graphite-containing electrode as recited in claim 4 , wherein the non-fiber particles are coated onto the surfaces of the fibers. 7. The graphite-containing electrode as recited in claim 4 , wherein the non-fiber particles reside interstitially in voids. 8. The graphite-containing electrode as recited in claim 1 , further comprising a binder holding the plurality of first graphite-containing elements and the plurality of second graphite-containing elements together. 9. The graphite-containing electrode as recited in claim 1 , further comprising oxygen-containing groups on a surface of the porous body. 10. A graphite-containing electrode comprising: a porous body including a plurality of first graphite-containing elements and a plurality of second graphite-containing elements intermingled with the plurality of first graphite-containing elements, the plurality of first graphite-containing elements having a first degree of graphitization and the plurality of second graphite-containing elements having a second, different degree of graphitization, wherein the first degree of graphitization is 20%, and the second degree of graphitization is 40%, and wherein one of the plurality of first graphite-containing elements and the plurality of second graphite-containing elements include portions that are amorphous carbon. 11. The graphite-containing electrode as recited in claim 10 , wherein the porous body includes, by weight, 20% of the plurality of first graphite-containing elements and 80% of the plurality of second graphite-containing elements.
