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

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