Abstract:
A nonaqueous electrolyte secondary battery according to an embodiment includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The negative electrode contains a negative electrode active material. A lithium insertion-extraction reaction potential of a negative electrode active material is higher than the oxidation-reduction potential of lithium by a value of 1 V or more. The nonaqueous electrolyte contains an electrolytic salt, a nonaqueous solvent, at least one hydroxyalkylsulfonic acid, and at least one sulfonate.
