    摘要： Provided is a nonaqueous electrolyte secondary battery which, even in the case of using a low-viscosity solvent having a narrow potential window, can increase the electrochemical stability of the nonaqueous electrolyte solution and suppress side reactions of the nonaqueous electrolyte solution during charge and discharge to reduce the degradation of the battery characteristics and has an excellent storage characteristic in high-temperature environments and a nonaqueous electrolyte solution for the nonaqueous electrolyte secondary battery. The nonaqueous electrolyte secondary battery includes: a positive electrode containing a positive-electrode active material; a negative electrode containing a negative-electrode active material; and a nonaqueous electrolyte solution containing a solute dissolved in a nonaqueous solvent, wherein the nonaqueous electrolyte solution further contains benzotrifluoride and a diisocyanate compound and the content of benzotrifluoride is 5% by volume or more in the nonaqueous electrolyte solution except the solute.
