Abstract:
In general, according to one embodiment, the active material for a battery contains a niobium composite oxide represented by the formula: LixM(1-y)NbyNb2O(7+δ). M represents at least one kind selected from the group consisting of Ti and Zr. X, y, and δ are numbers respectively satisfying the following: 0≦x≦6, 0≦y≦1, and −1≦δ≦1). The pH of the active material for a battery is from 7.4 to 12.5.
