Abstract
A supercapacitor comprising a cathode, an anode, a first single-walled carbon nanotube (SWNT) film electrode adjacent the cathode, a second SWNT film electrode adjacent the anode, and separator disposed between the first and second electrodes. The SWNT film electrodes may be manufactured by a non-filtration process comprising depositing the SWNT film on a foil via CVD; separating the SWNT film from the foil; heating the SWNT film; treating the SWNT film with an acid solution; washing the SWNT film; and excising the electrodes from the SWNT film.
