Abstract:
An object of the present invention 1 is to provide a non-aqueous electrolyte secondary battery having excellent general performance balance between durability performance and properties, such as a capacity, a resistance, and output characteristics. The present invention 1 is directed to a non-aqueous electrolytic solution for use in a non-aqueous electrolyte secondary battery which comprises: a positive electrode being capable of having occluded therein and releasing metal ions; a negative electrode being capable of having occluded therein and releasing metal ions, and comprising a negative electrode active material containing metal particles capable of forming an alloy together with Li and graphite particles; and a non-aqueous electrolytic solution comprising a non-aqueous solvent and an electrolyte dissolved in the non-aqueous solvent, wherein the non-aqueous electrolytic solution contains a compound represented by the general formula (A), and a non-aqueous electrolyte secondary battery using the non-aqueous electrolytic solution.
