PROBLEM TO BE SOLVED: To form an activated-carbon electrode which can instantaneously discharge a large current, can be handled easily, and has an excellent shock resistance by baking a molded composed of a powdery activated carbon, a vinylidene chloride polymer, and an organic material which is pyrolytically decomposed and form macro-pores when baked. SOLUTION: An activated-carbon electrode is obtained by baking a molded body of a raw material for the electrode containing activated carbon, vinylidene chloride polymer, and/or vinylidene chloride copolymer, and another organic material which is pyrolytically decomposed and forms macropores. Such a high polymer compound that is not melted, pyrolytically decomposed, nor sublimated at a temperature of <130 deg.C and has solubility in water of <=2w/w% (at 25 deg.C) and a molecular weight of >=1,000 is used as the organic material. The molded body of the raw material for electrode contains the activated carbon as an anhydride by 5-90wt.%, a partial structure derived from a vinylidene chloride monomer by 5-90wt.%, and the organic material 3-50wt.%. The molded body can also contain a molding assistant composed of a polysaccaride by 0.5-50wt.%. |
