PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery which hardly makes an organic solvent flow out from a battery container even when the battery is broken, which has high safety, less deterioration in performance caused by charging/discharging cycles by using a gelled nonaqueous electrolyte. SOLUTION: For example, ethylene carbonate is used as a solvent, vinylene carbonate and azobis isobutyronitrile are dissolved in ethylene carbonate, the solution obtained is impregnated in a positive material, a negative material, and a separator under reduced pressure, and block polymerization is conducted in a nitrogen atmosphere at 60 deg.C for 20 hours. In this process, gel containing ethylene carbonate is filled in micropores of the both electrodes and the separator. Then, they are immersed in a solution prepared by dissolving LiPF6 in ethylene carbonate to diffuse the gel, and thereby, the gel containing electrolyte is filled between electrodes. |
