PROBLEM TO BE SOLVED: To manufacture an active-carbon electrode having a high specific surface area with high productivity by molding a mixed powder of active-carbon powder and a thermosetting resin into a molded body with a predetermined shape through cold pressure molding and by heat-treating the molded body as it is in a non-oxidative atmosphere. SOLUTION: In a process 1, a solvent, e.g. acetone, etc., is added to active- carbon powder and a phenol resin as a thermosetting resin and kneaded. In a process 2, thus obtained kneaded material is dried in a vacuum at 50 deg.C for about 3 hours to remove the residual solvent, and in a following process 3, it is ground for example by attritor, etc., and further in a process 4, it is granulated into a predetermined grain size by passing through a mesh of about #70 for example. Then, in a process 5, thus obtained mixed powder is cold pressure molded into a molded body, and in a process 6, it is heat-treated in N2 gas atmosphere at 900 deg.C for 2 hours to carbonize the phenol resin to obtain an active-carbon electrode which is an active-carbon - carbon composite material. |
