Abstract
A nonaqueous electrolyte secondary battery according to the present invention is provided with a negative electrode, a positive electrode and a nonaqueous electrolyte. A negative electrode active material contained in the negative electrode contains a zinc manganese alloy containing Zn, Mn and Fe that is in an amount of 1,000 ppm or less of the total mass of Zn and Mn. With respect to the zinc manganese alloy, the molar ratio of the Zn content to the Mn content is from 3 to 13.
