Abstract
An activated electrode for a non-aqueous electrochemical cell is disclosed with a precursor thereof a lithium metal oxide with the formula x{zLiMnO.(1−z)LiM'O}.(1−x)LiMnMOfor 0<x<1; 0≦y≦0.5; and 0<z<1, comprised of layered zLiMnO.(1−z)LiM′Oand spinel LiMnMOcomponents, physically mixed or blended with one another or separated from one another in a compartmentalized electrode, in which M is one or more metal ions, and in which M′ is selected from one or more first-row transition metal ions, The electrode is activated by removing lithium and lithia, from the precursor. A cell and battery are also disclosed incorporating the disclosed positive electrode.
