PURPOSE:To provide an electrode material giving a pollution-free cell, having an H/C atomic ratio of falling within a specific range, and prepared by baking poly(alpha-halogenated acrylonitrile), poly(beta-halogenated acrylonitrile), etc. CONSTITUTION:A compound selected from poly(alpha-halogenated acrylonitrile), poly(beta-halogenated acrylonitrile), poly(halogenated dicyanoethylene), poly(cyanoacetylene) and poly(dicyanoacetylene) or their mixture is baked to obtain a carbonaceous material having an H/C atomic ratio of 0.010-0.55, and the material is used as the objective electrode material. |
