PROBLEM TO BE SOLVED: To provide a polymer electrolyte secondary battery equipped with a positive electrode capable of inhibiting the decomposition of a non-aqueous solvent in a non-aqueous electrolytic solution caused by repeated charging and discharging by using electroconductive ceramic powder in lieu of carbon as the electroconductive material. SOLUTION: A polymer electrolyte secondary battery includes an active material, electroconductive ceramic powder, a positive electrode 2 containing non-aqueous electrolytic solution and polymer for retaining it, and a negative electrode 4 containing active material to occlude and release lithium ions and retaining the non-aqueous electrolytic solution. The arrangement further includes a solid polymer electrolyte layer 5 interposed between the two electrodes 2, 4 and containing non-aqueous electrolytic solution and a polymer for retaining it. |
