Title: Process for producing carbon foams for energy storage devices

Abstract

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--1,000 m{sup 2}/g). Capacitances on the order of several tens of farad per gram of electrode are achieved. 9 figs.
