Lithium-iron-manganese complex oxide having a layered rock-salt structure and production method thereof |
| 摘要 |
A lithium-iron-manganese complex oxide having a layered rock-salt structure comprising a solid solution formed by dissolving lithium ferrite (LiFeO2) in Li2-xMnO3-y (0</=x</=2, 0</=y</=1) of a layered rock-salt structure in a homogeneous crystalline state in such a way that an iron rate satisfies the relationship of 0.2</=Fe/(Fe+Mn)</=0.75, wherein at least 10% of iron contained in said solid solution is in a tetravalent state. The lithium-iron-manganese complex oxide is useful as cathode materials for a next generation low-priced lithium-ion battery and catalyst materials. |
