Nonaqueous electrolyte solution and lithium secondary battery using same

A nonaqueous electrolytic solution wherein an electrolyte salt is dissolved in a nonaqueous solvent, comprising 0.01% to 30% by weight of at least one compound selected from the group consisting of 1,2-cyclohexanediol cyclic sulfite, hexahydro-1,3,2-benzodioxathiol-2,2-dioxide, and 1,2-cyclohexanediol derivatives represented by the following general formula (X), on the basis of the weight of the nonaqueous electrolytic solution:

• wherein R1 to R10 each independently represent a hydrogen atom, a C1 to C12 alkyl group, a C2 to C12 alkenyl group, a C2 to C12 alkynyl group, a C6 to C18 aryl group, or a C1 to C12 alkoxy group, and may bond to each other to form a ring structure, and any hydrogen atom of R1 to R10 may be substituted by a halogen atom, with the proviso that the case where all of R1 to R10 are hydrogen atoms is excluded;
• and X represents a >S═O group or a >C═O group.
