SCHICHTGITTERSTRUKTUR BESITZENDE LITHIUMHALTIGE METALLOXIDE, DIE FREI VON LOKALEN KUBISCH-SPINELL-ARTIGEN PHASEN SIND, UND HERSTELLUNG DERSELBEN |
摘要 |
The present invention includes substantially single-phase lithium metal oxide compounds having hexagonal layered crystal structures that are substantially free of localized cubic spinel-like structural phases. The lithium metal oxides of the invention have the formula Li<SUB>alpha</SUB>M<SUB>beta</SUB>A<SUB>gamma</SUB>O<SUB>2</SUB>, wherein M is one or more transition metals, A is one or more dopants having an average oxidation state N such that +2.5<=N<=+3.5, 0.90<=alpha<=1.10, and beta+gamma=1. The present invention also includes dilithiated forms of these compounds, lithium and lithium-ion secondary batteries using these compounds as positive electrode materials, and methods of preparing these compounds. |
