Kaschmitter, J L; Mayer, S T; Pekala, R W

A high energy density capacitor incorporating a variety of carbon foam electrodes is described. The foams, derived from the pyrolysis of resorcinol-formaldehyde and related polymers, are high density (0.1 g/cc-1.0 g/cc) electrically conductive and have high surface areas (400 m[sup 2]/g-1000 m[sup 2]/g). Capacitances on the order of several tens of farad per gram of electrode are achieved. 9 figures.
