Abstract:
According to one embodiment, an active material containing a niobium titanium composite oxide is provided. The niobium titanium composite oxide has average composition represented by LiyNb2+xTi1−xO7+0.5x (0≤x≤0.5, 0≤y≤5.5). The niobium titanium composite oxide satisfies peak intensity ratios represented by the following formulae (1) to (3): 0.05≤(B/A)≤0.7 (1) 0.01≤(C/A)≤0.2 (2) 0≤(D/A)≤0.1 (3).
