The non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a lithium-ion conductive non-aqueous electrolyte, and the negative electrode includes a negative electrode current collector, a negative electrode active material layer provided on the surface of the negative electrode current collector, and covering at least a part of the negative electrode active material layer. A coating with lithium ion permeability on the surface. The coating includes a lithium compound containing element M, element A, element F, and lithium, and element M is selected from the group consisting of P, Si, B, V, Nb, W, Ti, Zr, Al, Ba, La, and Ta At least one of the elements A is at least one selected from the group consisting of S, O, N, and Br. The non-aqueous electrolyte contains a lithium salt and a non-aqueous solvent in which the lithium salt is dissolved, and the non-aqueous solvent contains a compound having a fluorine group. |
