| Zusammenfassung: | The present invention concerns a non-aqueous electrolyte secondary battery includes a cathode (2) capable of being electrochemically doped with and dedoped from lithium; an anode (3)capable of being electrochemically doped with and dedoped from lithium; and an immobilized non-aqueous electrolyte or a gel electrolyte (4) interposed between the cathode (2) and the anode (3) and obtained by mixing a low viscosity compound with or dissolving a low viscosity compound in a polymer compound. At least one kind of unsaturated carbonate or a cyclic ester compound is added to the low viscosity compound, so that storage characteristics and cyclic characteristics are improved. |
