ELECTRICALLY CONDUCTIVE PLASTIC COMPOSITE MEMBER AND PLASTIC CELL USING THE SAME

摘要

An object of this invention is to provide an electrically conductive plastic material having a high bulk density, a uniform density and a capability of being well impregnated by electrolyte, a method of producing the same, and a cell using the plastic material as an electrode active material. The electrically conductive plastic material comprises a polymer film of pyrroles synthesized by the electrolytic oxidative polymerization and a polymer film of aromatic amines synthesized and directly applied onto the above-mentioned polymer film by the electrolytic oxidative polymerization. The production method thereof comprises the step of synthesizing substituted and/or nonsubstituted pyrroles on the surface of the positive electrode by the electrolytic oxidative polymerization in the presence of a substituted and/or nonsubstituted aromatic sulfonic acide or a salt thereof, and the step of forming substituted and/or nonsubstituted aromatic amines by the electrolytic oxidative polymerization on the surface of the positive electrode in the presence of a substituted and/or nonsubstituted aromatic sulfonic acid or a salt thereof, using the obtained pyrrole polymer as the positive electrode or as a part of the positive electrode.
