Patent abstract
A lithium-titanium composite oxide includes a crystallite diameter not larger than 6.9×102 Å, and includes a rutile type TiO2, an anatase type TiO2, Li2TiO3 and a lithium titanate having a spinel structure. The rutile type TiO2, the anatase type TiO2 and Li2TiO3 each has a main peak intensity not larger than 7 on the basis that a main peak intensity of the lithium titanate as determined by the X-ray diffractometry is set at 100.
