Abstract

The present invention provides; (1) a polarizable electrode for electric double-layer capacitor, which comprises a solid active carbon obtained by pyrolyzing a mixture mainly containing an active carbon and a thermosetting resin and which has, on the surface and/or inside, discontinuous portions free from said solid active carbon; (2) a process for producing the above polarizable electrode for electric double-layer capacitor, which comprises heat-treating, as necessary, a mixture mainly containing an active carbon, a thermosetting resin and a fiber capable of vaporizing upon heating, to vaporize said fiber and then pyrolyzing the resulting material; and (3) an electric double-layer capacitor comprising at least a pair of the above polarizable electrodes for electric double-layer capacitor and an electrolyte impregnated between the polarizable electrodes.
The above polarizable electrode for electric double-layer capacitor is free from the drawbacks of conventional polarizable electrodes, has a low internal resistance and can be charged with or can discharge a large electric current of several amperes to several hundreds of amperes momentarily.
