    摘要: It is possible to obtain at high yield a carbonaceous material suitable for carbon electrodes of electrical double layer capacitors and having superior capacitance by means of a method comprising a halogenation treatment step wherein a halogenated dry-distilled charcoal is obtained by bringing a dry-distilled charcoal into contact with a halogen gas; and by a dehalogenation treatment step wherein a part or all of the above-mentioned halogen in said halogenated dry-distilled charcoal is eliminated. In addition, it is possible to obtain carbonaceous material for electrical double layer capacitors, which has a large capacitance at rapid discharge and excellent shape, by means of conducting a molding treatment step in which a molded article is made by crushing a dry-distilled charcoal and adding a binding agent; and a carbonization treatment step in which the above-mentioned molded article is heated in an inert gas atmosphere before conducting the halogenation treatment.
