Ester compound, and non-aqueous electrolyte solution and lithium secondary battery each using the ester compound
Abstract:
The present invention includes (1) an ester compound having a specific structure, (2) a nonaqueous electrolytic solution for lithium secondary battery comprising an electrolyte dissolved in a nonaqueous solvent and containing an ester compound having a specific structure in an amount of from 0.01 to 10% by weight of the nonaqueous electrolytic solution, which is excellent in initial battery capacity and cycle property, and (3) a lithium secondary battery comprising a positive electrode, a negative electrode and a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, wherein the nonaqueous electrolytic solution contains an ester compound having a specific structure in an amount of from 0.01 to 10% by weight of the nonaqueous electrolytic solution.
