ACTIVE MATERIAL FOR BATTERIES, NON-AQUEOUS ELECTROLYTE BATTERY AND BATTERY PACK

摘要

According to one embodiment, an active material for batteries includes a titanium composite oxide, wherein the titanium composite oxide includes a monoclinic &bgr;-type titanium composite oxide as a main phase, and when an integral intensity of the main peak of the monoclinic &bgr;-type titanium composite oxide obtained with a wideangle X-ray diffraction method having a CuKα-ray as an X-ray source is 100, the relative value of the integral intensity of the main peak that presents the range of 2&thetas;=25.1 to 25.5° attributed to at least one sub-phase selected from anatase-type TiO2 and H2Ti8O17 is 30 or less, and the titanium composite oxide has a crystallite diameter of 5 nm or more as calculated from the main peak of the monoclinic &bgr;-type titanium composite oxide obtained with the wideangle X-ray diffraction method.
