<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic solution which hardly bloats a battery due to decomposed gases and excellent in charge and discharge properties of the battery, and a secondary battery which includes the electrolytic solution, hardly bloats, and is excellent in the charge and discharge properties. <P>SOLUTION: The nonaqueous electrolytic solution is featured by including a nonaqueous solvent and a lithium salt, wherein the nonaqueous solvent is a solvent with an unsaturated carbon hydride having 6-16C (a) which is a chemical compound composed of carbon, fluorine and hydrogen having at least one carbon-carbon bonds unsaturated bonds group in a molecular structure is melted therein. The secondary battery furthermore comprises a negative and a positive electrodes capable of storing and releasing lithium, and the nonaqueous electrolytic solution. <P>COPYRIGHT: (C)2004,JPO |
