Abstract
The present invention includes [1] a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing from 0.001 to 5% by mass of a specified acyclic lithium salt in the nonaqueous electrolytic solution and being capable of improving electrochemical characteristics in a broad temperature range; and [2] an energy storage device including a positive electrode, a negative electrode, and a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing from 0.001 to 5% by mass of a specified acyclic lithium salt in the nonaqueous electrolytic solution.
