Abstract

Electrodes, which may be composite capacitor electrodes, include carbon fibers, illustratively chopped carbon fibers having an aspect ratio of from about 100-5000, have been treated with a non-ionic surfactant, specifically the polyoxyethyleneglycol octophenyl ether, Triton X-100, to increase the hydrophilicity of the fibers. The capacitive electrodes prepared with the surface-modified carbon fibers exhibit increased charge acceptance.
