A Co-based 5V spinel-type lithium-manganese-containing complex oxide which not only has an operating potential of 4.5 V or more, but also can enlarge the capacity region in the range of 5.5 to 5.0 V and can increase the energy density. , Which is represented by the general formula [Li x (Co y Mn 3-xy ) O 4 -δ] (where 0.90 ? X ? Type lithium-cobalt manganese complex oxide having a crystallite size of 100 nm to 200 nm, an interatomic distance of Li-O of 1.80 Å to 2.00 Å and a distortion of 0.20 to 0.50, as measured by a Rietveld method using a fundamental method Spinel type lithium cobalt manganese complex oxide. |
