Abstract
A self-supporting carbon electrode can include, or consist essentially of, nanostructured carbon, for example, oxygen-functionalized nanostructured carbon.
Claims13
A self-supporting carbon electrode comprising nanostructured carbon, wherein the nanostructured carbon has a length greater than 100 μm and less than 1,000 μm,
- wherein the self-supporting carbon positive electrode consists essentially of nanostructured carbon and the nanostructured carbon is oxygen-functionalized nanostructured carbon;
- and
- the self-supporting carbon positive electrode has a thickness of 10 μm or greater.
An energy storage device comprising a self-supporting carbon electrode comprising oxygen-functionalized nanostructured carbon,
- wherein the self-supporting carbon positive electrode consists essentially of nanostructured carbon and the nanostructured carbon is oxygen-functionalized nanostructured carbon;
- and
- the self-supporting carbon electrode has a thickness of 10 μm or greater.
