Abstract

According to one embodiment, there is provided a nonaqueous electrolyte battery (100). The nonaqueous electrolyte battery (100) includes a negative electrode (2), a positive electrode (3), and a nonaqueous electrolyte. The positive electrode (3) includes a nickelcobalt-manganese composite oxide represented by a composition formula Li<1-a>Ni<x>Co<y>Mn<z>O<2>. Subscripts x, y, and z satisfy an inequality 0.1 ≤ x/(y + z) ≤ 1.3, and subscript a satisfies 0 ≤ a ≤ 1. A ratio A<S>/A<Ni>of an S atom abundance ratio As to an Ni atom abundance ratio A<Ni>of a surface of the positive electrode (3) is 0.4 to 5. A ratio p/n of a capacity p of the positive electrode (3) to a capacity n of the negative electrode (2) is within a range of 1.2 to 2.
