Reacting MnO, a lithium compound and a bismuth compound produces a lithium battery cathode material for lithium electrochemical systems. The same results can also be achieved by reacting MnO, lithium, or a compound containing lithium and bismuth, or a compound containing bismuth. Manganese based mixed metal oxides with lithium and bismuth were initially examined as a cathode material for rechargeable lithium and lithium-ion batteries in order to provide a new mixed metal oxide cathode material as the positive electrode in rechargeable lithium and lithium ion electrochemical cells. A stable mixed metal oxide was fabricated through a solid-state reaction between manganese dioxide, a lithium compound and bismuth or a bismuth compound. In addition to the lithium battery cathode material, a lithium manganese bismuth mixed metal oxide cathode, a lithium electrochemical system with a lithium manganese bismuth mixed metal oxide and a rechargeable lithium battery with a lithium manganese bismuth mixed metal oxide cathode are also provided. These devices provide much improved sustained specific capacity of about 120 mAhrs/g and the material exhibits an inherent catalytic behavior for charge transfer.

The present invention provides a manganese bismuth mixed metal oxide cathode material through a solid-state reaction between manganese dioxide, and either bismuth or a bismuth compound in a compound having the general formula MnO(BiO), which affords charge transfer catalytic behavior that allows the cathode to be fully reversible at suppressed charge potentials and increased discharge potentials. The MnO(BiO)cathode material may be incorporated into an electrochemical cell with either a lithium metal or lithium ion anode and an organic electrolyte. The present invention provides a compound with the general formula MnO(BiO), where subscript x is between 0.05 and 0.25, subscript y is about 2 and the overcharge protection is not needed as the subscript z approaches 0.0. In the preferred embodiment, a cathode material where subscript x is between 0.05 and 0.135 with the formula MnO(BiO)provides the much-needed full reversibility, high voltage stability and reduced charge transfer impedance. A manganese bismuth mixed metal oxide cathode for an lithium electrochemical system, a lithium electrochemical system and a rechargeable lithium battery employing the same compound with the general formula MnO(BiO)and methods for making manganese bismuth mixed metal oxide cathode material for lithium electrochemical devices having the general formula MnO(BiO)are also provided.
