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 LiSUBalpha/SUBMSUBbeta/SUBASUBgamma/SUBOSUB2/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.
