To provide a nonaqueous electrolytic solution secondary battery with a high energy density, having a high charging/discharging efficiency and showing a superior charging/discharging cycle, by suppressing decomposition of the electrolytic solution.
This battery comprises a negative electrode having a current collector and a coating film of an active material containing a noncarbon material capable of storing and releasing lithium formed on the current collector; a positive electrode capable of storing and releasing lithium; and an electrolytic solution in which a lithium salt is dissolved in a nonaqueous solvent. The electrolytic solution contains a chemical compound expressed in a general formula (I). In the formula (I), R
