Beschreibung
Zusammenfassung:	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 LialphaMbetaAgammaO2, wherein M is one or more transition metals, A is one or more dopants having an average oxidation state N such that +2.5
