Abstract
An activated electrode for a non-aqueous electrochemical cell is disclosed with a precursor of a lithium metal oxide with the formula xLi2MnO3.(1−x)LiMn2−yMyO4 for 0<x<1 and 0≦y<1 in which the Li2MnO3 and LiMn2−yMyO4 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.
