US Patent 7435476 - Functionalized nanotube material for supercapacitor electrodes

This patent is based on a collaboration of Honda and Ohio State University and teaches a way to fabricate carbon nanotube supercapacitors with higher levels of capacitance. Claim 1 reads:

1. A method of producing electrodes comprising:

chemically oxidizing carbon nanotube-containing material at a temperature of less than about 200 C.;

contacting the oxidized carbon nanotube-containing material with functional groups to form functionalized carbon nanotube-containing material; and

preparing electrodes from the functionalized carbon nanotube-containing material, wherein the carbon nanotube-containing material is substantially free of binder materials.
