Abstract
According to one embodiment, there is provided an active material. The active material includes a titanium-containing oxide. The titanium-containing oxide is represented by a general formula of Li(2+w)Na(2−x)M1(x/2)Ti(6−y)M2zO14. In the general formula, the subscripts w, x, y and z are within ranges of 0≤w≤6, 0<x<2, 0≤y≤3, and 0≤z≤3, respectively. M1 is at least one metallic element selected from the group consisting of Sr, Ba, and Pb. M2 is at least one element selected from the group consisting of metallic elements M (excluding Ti and M1) and P.
