Abstract
A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. A positive electrode charge potential is 3.7 V or less with respect to a lithium metal potential. The nonaqueous electrolyte includes a cyclic disulfone compound having a specific structure in an amount of 0.1 to 4.0% by mass based on a total mass of the nonaqueous electrolyte.
