A non-aqueous electrolyte secondary battery with high energy density, which suppresses decomposition of an electrolyte, has high charge / discharge efficiency, and exhibits excellent charge / discharge cycle characteristics. A negative electrode having a current collector, a coating of an active material containing a non-carbon material capable of occluding and releasing lithium formed on the current collector, and occluding and releasing lithium A non-aqueous electrolyte secondary battery comprising a possible positive electrode and an electrolyte obtained by dissolving a lithium salt in a non-aqueous solvent. The electrolyte contains a compound represented by the following general formula (I). Embedded image (In the formula, X represents fluorine or a perfluoroalkyl group having 1 to 3 carbon atoms, and 2n Xs may be the same or different. N represents an integer of 1 or more.)
