Abstract
Disclosed are a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, which contains a sulfonate compound having a specific structure in an amount of from 0.01 to 10% by mass of the nonaqueous electrolytic solution, and an electrochemical device containing the nonaqueous electrolytic solution. The nonaqueous electrolytic solution is excellent in the effect of improving the storage property of primary batteries and improving the cycle property of secondary batteries in use thereof at high temperatures and the low-temperature property thereof after high-temperature cycles.
