<P>PROBLEM TO BE SOLVED: To obtain a nonaqueous electrolyte secondary battery excellent in charge and discharge characteristics through restraint of side reaction generated due to charge and discharge between a nonaqueous solvent used in the nonaqueous electrolyte solution and an anode, even if an anode active material containing silicon is used for the anode, by improvement of the nonaqueous electrolyte solution used for the nonaqueous electrolyte secondary battery. <P>SOLUTION: In the nonaqueous electrolyte secondary battery provided with a cathode 11, an anode 12 and nonaqueous electrolyte solution with electrolyte dissolved in a nonaqueous solvent, the nonaqueous electrolyte solution contains a compound expressed in a general formula: (AFx)-B (in the formula, AFx is a group having a perfluoro cycloalkane structure, and B is a group having a carbonyl group). <P>COPYRIGHT: (C)2011,JPO&INPIT |
