ELECTRODE MATERIAL FOR ELECTRIC DOUBLE LAYER CAPACITOR AND PROCESS FOR PRODUCING THE SAME, ELECTRODE FOR ELECTRIC DOUBLE LAYER CAPACITOR, AND ELECTRIC DOUBLE LAYER CAPACITOR

摘要

This invention provides an electrode material for an electric double layer capacitor, which can provide an electric double layer capacitor having low internal resistance and large electrostatic capacitance, a process for producing the same, and an electrode for an electric double layer capacitor and an electric double layer capacitor using the electrode material. The electrode material is characterized by comprising a carbonaceous substance and activated carbon, the carbonaceous substance having been produced by heat treating or activating a fullerene-containing soot, or an extraction residue obtained by substantially extracting at least a part of fullerene from a fullerene-containing soot with a solvent. The electrode for an electric double layer capacitor and the electric double layer capacitor are characterized by using the electrode material.
