Zusammenfassung:Provided is a nonaqueous electrolyte secondary battery capable of suppressing resistance increase in long-term storage at high temperatures. A nonaqueous electrolyte secondary battery disclosed here includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes a positive electrode current collector, and a positive electrode active material layer supported by the positive electrode current collector. The positive electrode active material layer includes a positive electrode active material, and at least one positive electrode additive selected from the group consisting a thiophosphate salt and a dithiophosphate salt.
