METHOD FOR MANUFACTURING CARBON ELECTRODE FOR ELECTRIC DOUBLE LAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a carbon electrode for the electric double layer capacitor without deterioration in the electrode characteristic by uniformizing dispersion of carbon in a molded body and preventing carbon residue after sintering. SOLUTION: A carbide powder is made by slurry method in the method of manufacturing the carbon electrode for the electric double layer capacitor with the use of polyvinylidene chloride resin carbide powder. Resol-based phenol resin is used for the binder. Ion electrolyte is added to the slurry in the forming process. Ion concentration of the ion electrolyte in the slurry is set to be 200 ppm or more.
