Abstract

According to one embodiment, a battery active material includes a complex oxide containing Nb and Ti and an element M. In the active material, the molar ratio (M/Ti) of the element M to Ti satisfies the following formula (I): 0<M/Ti≤0.5 (I). In the complex oxide containing Nb and Ti, the molar ratio (Nb/Ti) of Nb to Ti satisfies the following formula (II): 0≤Nb/Ti≤5 (II). The element M is at least one selected from the group consisting of B, Na, Mg, Al, Si, S, P, K, Ca, Mo, W, Cr, Mn, Co, Ni, and Fe.
