A cathode for a lithium battery includes LiNiMnMOwhere M is at least one selected from the group consisting of Mo, Ti, Cr, Zr and V, and x is between 0.005-0.02. The LiNiMnMOcan be coated with MnPO. The MnPOcan be 1-3 wt. %, based on the total weight of the LiNiMnMOand MnPO. A cathode composition, a lithium battery, and a method of making a lithium battery are also disclosed.

Early transition metal stabilized high capacity cobalt free cathodes for lithium-ion batteries

A battery includes a redox flow anode chamber coupled to an anode current collector, a separator, and an external container in fluid connection with the redox flow anode chamber. The external container has therein a solid phosphorus material. A first redox-active mediator and the second redox-active mediator are circulated through the half-cell electrode chamber and the external container. During a charging cycle the first redox-active mediator is reduced at the current collector electrode and the reduced first mediator reduces the phosphorus material, and wherein during a discharging cycle the second redox-active mediator is oxidized at the anode current collector electrode, and the second redox-active mediator is then reduced by the reduced phosphorus material. A method of operating a battery and a method of making a battery are also discussed.
