Abstract
A nonaqueous electrolyte secondary battery proposed herein is configured such that a positive-electrode active material layer includes graphite particles and a gas generant. Further, an electrolyte solution includes an α solute. Here, a relationship between an upper limit electric potential X of a positive electrode in a predetermined normal use area, an electric potential Y at which an amount of the α solute in the electrolyte solution begins to decrease due to the graphite particles, and an electric potential Z at which the gas generant begins to generate gas is X<Y<Z.
