ABSTRACT:
An electrode for a capacitor includes a substrate comprising at least one of glassy carbon and a metal. According to various embodiments, the substrate may be provided as glassy carbon or any of a variety of metals for use in capacitors. The capacitor also includes an activated carbon material adjacent the substrate. The activated carbon layer includes oxygen-containing functional groups. A material is provided in contact with the activated carbon layer for providing enhanced capacitance for the electrode. Various types of capacitance-enhancing materials may be utilized, including carbon nanotubes and conductive metal oxides.
