Title: Lithium metal oxide electrodes for lithium cells and batteries

Abstract

A lithium metal oxide positive electrode for a non-aqueous lithium cell is disclosed. The cell is prepared in its initial discharged state and has a general formula xLiMO.sub.2.(1-x)Li.sub.2 M'O.sub.3 in which 0<1, and where M is one or more trivalent ion with at least one ion being Mn or Ni, and where M' is one or more tetravalent ion. Complete cells or batteries are disclosed with anode, cathode and electrolyte as are batteries of several cells connected in parallel or series or both.
