A negative electrode active material includes graphite and silicon oxide. On a rectangular coordinate system having an SOC of the battery on a horizontal axis and a dimension of the battery on a vertical axis, a charging profile of the battery includes a first stage and a second stage. When the battery is charged at a current rate equal to or higher than an inherent current rate, a first slope is less steep than a second slope. When the battery is charged at a current rate lower than the inherent current rate, the first slope is steeper than the second slope.
