<P>PROBLEM TO BE SOLVED: To provide an active material for battery having excellent charge/discharge cycle performance, a nonaqueous electrolyte battery containing the active material and having excellent charge/discharge cycle performance, and a battery pack including the nonaqueous electrolyte battery. <P>SOLUTION: According to an embodiment, an active material for battery containing a monoclinic system β type titanium composite oxide is provided. The monoclinic system β type titanium composite oxide contains a first element consisting of at least one of Mo and W, and satisfies a formula (1); B>A. A is the intensity of peak attributed to a (110) plane of the monoclinic system β type titanium composite oxide in a wide-angle X-ray diffraction pattern thereof. B is the intensity of peak attributed to a (002) plane of the monoclinic system β type titanium composite oxide in the wide-angle X-ray diffraction pattern thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
