An activated electrode for a non-aqueous electrochemical cell is disclosed with a precursor of a lithium metal oxide with the formula xLi<SUB>2</SUB>MnO<SUB>3</SUB>.(1-x)LiMn<SUB>2-y</SUB>M<SUB>y</SUB>O<SUB>4 </SUB>for 0<x<1 and 0<=y<1 IN WHICH THE LI<SUB>2</SUB>MnO<SUB>3 </SUB>and LiMn<SUB>2-y</SUB>M<SUB>y</SUB>O<SUB>4 </SUB>components have layered and spinel-type structures, respectively, and in which M is one or more metal cations. The electrode is activated by removing lithia, or lithium and lithia, from the precursor. A cell and battery are also disclosed incorporating the disclosed positive electrode.
