ABSTRACT:
An activated electrode for a non-aqueous electrochemical cell is disclosed with a precursor thereof a lithium metal oxide with the formula x{zLi2MnO3•(1-z)LiM′O2}.(1-x)LiMn2−yMyO4for 0<x<1; 0≦y≦0.5; and 0<z<1, comprised of layered zLi2MnO3.(1-z)LiM′O2and spinel LiMn2−yMyO4components, 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.
