摘要:
A transition metal oxide containing solid solution lithium according to the present invention contains a transition metal oxide containing lithium, which is represented by a chemical formula: Li 1.5 [Ni a Co b Mn c [Li] d ]O 3 (where Li is lithium, Ni is nickel, Co is cobalt, Mn is manganese, O is oxygen, a, b, c and d satisfy relationships: 0 2 MnO 3 with a layered structure in a region to be changed to the spinel structure to LiMn 2 O 4 with the spinel structure is defined to be 1, a spinel structure change ratio of the transition metal oxide containing lithium is 0.25 or more to less than 1.0.
