摘要:
A nonaqueous electrolyte secondary battery includes an electrode group having a positive electrode and a negative electrode wound flatly by way of an interposed separator, a positive electrode tab electrically connected to the positive electrode, and projecting from a spiral winding surface of the electrode group, a negative electrode tab electrically connected to the negative electrode, and projecting from the spiral winding surface, and a nonaqueous electrolyte, wherein the nonaqueous solvent contains sultone compound including a ring having at least one double bond, and a distance between the positive electrode tab and the negative electrode tab is 6 mm to 18 mm.
