Abstract:
The present invention provides a nonaqueous electrolytic solution in which an electrolyte salt is dissolved in a nonaqueous solvent, containing 0.01% to 30% by weight of a 1,2-cyclohexanediol derivative having a specific structure; and a lithium secondary battery using the nonaqueous electrolytic solution. The lithium secondary battery exhibits excellent battery characteristics such as electrical capacity, cycle property, and storage property and can maintain excellent long-term battery performance.
