Abstract
Graphitic nanofibers, which include tubular fullerenes (commonly called “buckytubes”), nanotubes and fibrils, which are functionalized by chemical substitution, are used as electrodes in electrochemical capacitors. The graphitic nanofiber based electrode increases the performance of the electrochemical capacitors.
