Abstract
According to one embodiment, a nonaqueous electrolyte battery including a negative electrode, a positive electrode, and a nonaqueous electrolyte is provided. The negative electrode contains a negative electrode active material. The positive electrode contains a positive electrode active material. The negative electrode active material contains a titanium-containing composite oxide. The positive electrode active material contains secondary particles of a first composite oxide and primary particles of a second composite oxide. The first composite oxide is represented by a general formula LiMnMgFePO(0<x≤0.1, 0<y≤0.3). The second composite oxide is represented by a general formula LiCoNiMnO(0≤a, b≤0.5).
