Nonaqueous electrolyte secondary battery

A nonaqueous electrolyte secondary battery comprising a positive electrode, a negative electrode, a separator disposed between the positive electrode and the negative electrode, and a nonaqueous electrolyte, wherein

• the negative electrode includes an opposing region that opposes the positive electrode with the separator disposed therebetween and a non-opposing region that does not oppose the positive electrode but opposes the separator, and
• configured such that a discharge cut-off voltage of the nonaqueous electrolyte secondary battery is in a range of 2.5 V to 3.0 V, and a part of the non-opposing region adjacent to a boundary between the opposing region and the non-opposing region has an electric potential plateau in a range of −0.02 V to +0.02 V relative to a negative electrode potential in the opposing region,
• wherein the part of the non-opposing region adjacent to the boundary is a region that extends toward the non-opposing region from the boundary by 1 mm to 2 mm, and
• the non-opposed region comprises lithium.
