Abstract
According to one embodiment, a nonaqueous electrolyte battery includes a container, a positive electrode, and a negative electrode. The container satisfies Formula (1) of 0.15≦(Tmin/Tmax)≦1. The positive electrode includes a positive electrode active material represented by the composition formula Li1-aNixCoyMnzO2. The negative electrode includes a spinel type lithium titanium oxide. A nominal capacity of the nonaqueous electrolyte battery is in a range of from 5 Ah to 200 Ah. When a state of charge based on the nominal capacity is 50%, an open circuit voltage is in a range of from 2.12 V to 2.24 V.
