PURPOSE: To stably obtain an active carbon electrode which is high in electrostatic capacitance and quality by a method wherein a carbide is subjected to a primary activation treatment to serve as a carbon material, binder is added to the carbon material, the binder-loaded carbon material is molded, and the molded body is subjected to a carbonization treatment and then to a secondary activation treatment. CONSTITUTION: Novolak phenolic resin is cured and then ground into particles prescribed in size, the resin particles are carbonized by a thermal treatment carried out in a nitrogen atmosphere. In succession, the carbonized particles are thermally treated into granular activated carbon material in a carbon dioxide gas atmosphere through a primary activation treatment. The granular activated carbon material is ground into powder, and phenolic resin, ethanol, and creosote are mixed as binder into the activated carbon powder, which is kneaded well and molded into a plate-like piece. The molded plate-like piece is subjected to a carbonization treatment in a nitrogen atmosphere, and thermally treated into a plate-like activated carbon in a carbon dioxide gas atmosphere through a secondary activation treatment. By this setup, an active carbon electrode high in electrostatic capacitance and quality can be stably obtained. |
