Abstract:
The present invention provides a nonaqueous electrolytic solution exhibiting excellent battery characteristics such as electrical capacity, cycle property and storage property and capable of maintaining the battery characteristics for a long tire, and a lithium secondary battery using the nonaqueous electrolytic solution.A nonaqueous electrolytic solution for a lithium secondary battery, in which an electrolyte salt is dissolved in a nonaqueous solvent, containing 0.1 to 10% by weight of an ethylene carbonate derivative represented by the general formula (I) shown below, and 0.01 to 10% by weight of (A) a triple bond-containing compound and/or (B) a pentafluorophenyloxy compound represented by the general formula (X) shown below: wherein R1 to R3 each independently represents a hydrogen atom, a halogen atom, an alkenyl group, an alkynyl group or an aryl group, provided that ethylene carbonate is excluded from the definition of the ethylene carbonate derivative, wherein R15 represents an alkylcarbonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group or an alkanesulfonyl group.
