PROBLEM TO BE SOLVED: To provide a high-molecular solid electrolyte battery, of which cycle characteristic is improved, by forming a battery of a negative electrode, a positive electrode and the high-molecular solid electrolyte, which contacts the negative electrode active material and which contains the heterocyclic compound including double-coupled element. SOLUTION: In a high-molecular solid electrolyte battery, which is formed of a negative electrode, a positive electrode and the high-molecular electrolyte, as the high-molecular solid electrolyte, polyethylene oxide, which contains the heterocyclic compound having a double-coupled element such as thiophene at 0.05-5% by weight and which contains the organic matter plasticizer such as ethylene carbonate at need, is used. The negative electrode is desirably made of lithium or the carbonaceous material, and the high-molecular solid electrolyte contacts this negative electrode active material. The high-molecular solid electrolyte is desirable formed integrally with the negative electrode and/or the positive electrode. Affinity of the high-molecular solid electrolyte to the active material is thereby improved, and the power generating ability and the battery cycle characteristic can be improved. |
