TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Battery: The electrolytic solution battery further contains lithium tetrafluoroborate. In the battery, the positive electrode, the negative electrode and the non-aqueous electrolytic solution are contained in an exterior member composed of a laminated film. The electrolytic solution battery contains a polymer compound which is swollen by the non-aqueous electrolytic solution.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Solution: The electrolytic solution further contains lithium tetrafluoroborate, where the content of lithium tetrafluoroborate in the non-aqueous electrolytic solution is 0.05-0.5 mass.%. Preferred Components: The halogenated cyclic carbonates are a fluorinated cyclic carbonate (preferably fluoroethylene carbonate) and a chlorinated cyclic carbonate (preferably chloroethylene carbonate). The mass ratio of the fluorinated cyclic carbonate to the chlorinated cyclic carbonate in the non-aqueous electrolytic solution is 1/1 to 1/10.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polymer compound is polyvinylidene fluoride. SPECIFIC COMPOUNDS - 5 Compounds are disclosed as the halogenated cyclic carbonates, i.e. 4-fluoro-1,3-dioxolan-2-one(fluoroethylene carbonate) (IA); trans-4,5-difluoro-fluoro-1,3-dioxolan-2-one(difluoroethylene carbonate); trifluoropropylene carbonate; 4-chloro-1,3-dioxolan-2-one(chloroethylene carbonate); and trichloropropylene carbonate.    EXAMPLE - An electrolytic solution was prepared by mixing ethylene carbonate, ethylmethyl carbonate, lithium hexafluorophosphate, fluoroethylene carbonate and chloroethylene carbonate in a proportion (mass ratio) of 33.4/51/15/0.5/0.1. A laminate type battery was prepared using the electrolytic solution. It was found that, two kinds of halogenated cyclic carbonates containing a different halogen element from each other (fluoroethylene carbonate or difluoroethylene carbonate and chloroethylene carbonate) in the non-aqueous electrolytic solution, the change in the thickness of the battery at the time of storage at 90 degrees C for 4 hours reduced as compared with comparative not containing chloroethylene carbonate in the non-aqueous electrolytic solution.
