According to one embodiment, a nonaqueous electrolyte battery including a positive electrode, a negative electrode, and a nonaqueous electrolyte is provided. The positive electrode includes an active material including Li 1−x Mn 2−y−z Al y M z O 4 (−0.1≤x≤1, 0.20≤y≤0.35, 0≤z≤0.1, M is at least one metal selected from Mg, Ca, Ti, V, Cr, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, and Sn). The negative electrode includes an active material including a first oxide represented by Li 4+a Ti 5 O 12 (−0.5≤a≤3) and a second oxide of at least one element selected from Al, Co, Cr, Cu, Fe, Mg, Ni, Zn, and Zr. The second oxide is included in an amount of from 300 ppm to 5000 ppm relative to a weight of the first oxide. |
