Abstract
According to one embodiment, a nonaqueous electrolyte battery includes a nonaqueous electrolyte, a positive electrode, a negative electrode and a separator. The nonaqueous electrolyte includes an asymmetric sulfone-based compound and a symmetric sulfone-based compound. The positive electrode includes a composite oxide represented by Li1−xMn1.5−yNi0.5−zMy+zO4 (0≦x≦1, 0≦y+z≦0.15, and M is at least one kind of element selected from the group consisting of Mg, Al, Ti, Fe, Co, Ni, Cu, Zn, Ga, Nb, Sn, Zr and Ta). The negative electrode includes a Ti-containing oxide which is capable of absorbing and releasing lithium. The separator includes a nonwoven fabric.
