PURPOSE:To retard the decomposition of electrolyte and the degradation of active material caused by overcharge by using a complex comprising specified two or more polymers in a positive electrode. CONSTITUTION:A complex comprising an aniline polymer, indicated in the formula, prepared by electrochemical polymerization or chemical polymerization and one or more polymers selected from thiophene polymer, pyrrole polymer, and paraphenylene polymer, which have doping potential equal to or higher than the aniline polymer is used in a positive electrode. Alkali metal (alloy), conductive polymer, or a complex of alkali metal alloy and conductive polymer is used in a negative electrode. By this constitution, the degradataion of active material and electrolyte caused by repeated charge-discharge can be retarded. In the formula, R1-R4 show H, alkyl, alkoxy, or allyl of 1-10C, and aryl of 6-10C. |
