Abstract:
An object of the present invention is to provide a non-aqueous electrolytic solution which can improve a non-aqueous electrolyte secondary battery in high-temperature storage characteristics and load characteristics, and a non-aqueous electrolyte secondary battery using the non-aqueous electrolytic solution. The present invention is directed to a non-aqueous electrolytic solution for use in a non-aqueous electrolyte secondary battery which comprises a positive electrode and a negative electrode each being capable of having occluded therein and releasing metal ions, wherein the non-aqueous electrolytic solution contains an electrolyte, a non-aqueous solvent, and a compound represented by the following general formula (A): wherein each of R1, R2, and Y represents a hydrocarbon group having 1 to 12 carbon atoms and optionally having a substituent, and X represents a hydrogen or fluorine atom, wherein R1, R2, and Y are the same or different.
