Abstract: Powder of a polymer active material 1 exhibiting an electro-chemical oxidation-reduction reaction is mixed with powder of a conductivity assisting agent 2 to obtain a mixture. The mixture is molded by a thermal press into a unitary block. Thus, a cell electrode having a large film thickness is produced without causing cracks or breakage. The electrode having a large film thickness improves the energy density of the polymer secondary cell.

Abstract: Electroconductive polymers of different kinds are doped with an anion which is the same as that derived from a single acid that occupies the most part of an electrolytic solution of a polymer battery. A cathode and an anode are manufactured from the electroconductive polymers. These electrodes and a protonic acid having a pKa value in a first dissociation stage in water of at least pKa<2 as the single acid that occupies the most part of the electrolytic solution. Use of the electrodes and the electrolytic solution of the protonic acid can give rise to a polymer battery that is prevented from deterioration of characteristics of its electrodes with a lapse of time accompanied by repeated charging and discharging and retains high operation voltage as well as improved cycle characteristics and discharge current density.
