Abstract
According to one embodiment, there is provided a nonaqueous electrolyte battery including a positive electrode, a negative electrode, a nonaqueous electrolyte and a separator. The positive electrode includes a positive electrode active material containing LiNiCoMnMO(0.9<x≤1.25, 0<a≤0.4, 0≤b≤0.45, 0≤c≤0.1, and M represents at least one element selected from the group consisting of Mg, Al, Si, Ti, Zn, Zr, Ca, and Sn). The separator includes polyester. A pore volume in a pore size distribution according to a mercury intrusion porosimetry is in a range of 0.9 cm/g to 3 cm/g. An air permeability value according to a Gurley method is in a range of 2 sec/100 ml to 15 sec/100 ml.
