Patent ID: 8541137

Claim:
A nonaqueous electrolyte battery, comprising: a case; a positive electrode provided in the case and comprising at least one selected from the group consisting of spinel type lithium-manganese-nickel composite oxide and lithium phosphate oxide having an olivine structure; a negative electrode provided in the case and containing a lithium-titanium composite oxide comprising a crystallite diameter not larger than 6.9×10 2 Å; and a nonaqueous electrolyte provided in the case; wherein in a X-ray diffractometry curve of the lithium-titanium composite oxide, none of a main peak intensity of a rutile type TiO 2 , a main peak intensity of an anatase type TiO 2 and a main peak intensity of Li 2 TiO 3 is larger than 7 when a main peak intensity of a lithium titanate having a spinel structure is set at 100.
