Abstract
An active material includes an NbTiOphase and at least one Nb-rich phase selected from an NbTiOphase, an NbTiOphase, and an NbTiOphase. The active material satisfies a peak intensity ratio represented by the following Formula (1): 0<I/I≤0.25 (1). In Formula (1), Iis a peak intensity of the maximum peak attributed to the NbTiOphase and appealing at 2θ of 26.0±0.1° in a wide angle X-ray diffraction pattern under CuKα rays as an X-ray source, and Iis a peak intensity of the maximum peak attributed to the at least one Nb-rich phase and appearing at 2θ of 24.9±0.2° in the diffraction pattern.
