Nonaqueous electrolytic solution and lithium secondary battery

摘要

A nonaqueous electrolytic solution for a lithium secondary battery, in which 0.01 to 10 wt. % of a sulfur-containing acid ester and 0.01 to 10 wt. % of a triple bond-containing compound are dissolved in a nonaqueous solvent, and a lithium secondary battery employing the nonaqueous electrolytic solution.
