摘要：
A nonaqueous electrolyte battery, containing a case and provided in the case, a positive electrode, a negative electrode and a nonaqueous electrolyte. The negative electrode comprises a lithium-titanium composite oxide, wherein a crystallite diameter of the lithium-titanium composite oxide is not larger than 6.9×102 Å. The lithium-titanium composite oxide comprises: rutile TiO2; anatase TiO2; Li2TiO3; and a lithium titanate having a spinel structure. A main peak intensity relative to lithium titanate set at 100, as determined by X-ray diffractometry, of each of lithium titanate having a spinel structure, the rutile TiO2, the anatase TiO2 and Li2TiO3 is not larger than 7.
