Abstract: Methods for synthesizing crystalline Ni-rich cathode materials are disclosed. The Ni-rich cathode material may have a formula LiNiXMnyMzCo1-x-y-zO2, where M represents one or more dopant metals, x?0.6, 0.01?y<0.2, 0?z?0.05, and x+y+z?1.0. The methods are cost-effective, and include methods for solid-state, molten-salt, and flash-sintering syntheses.

Abstract: The present technology discloses lithium metal polyanion (LMX) cathode compounds which contain a mixture of SiO4 and PO4 anions. Compounds based on silicate SiO4 anions can exhibit significantly higher gravimetric capacities than conventional lithium iron phosphate (LFP) materials. The present technology offers electrochemical advantages of the LMX compounds over compounds fabricated with only SiO4 anions. Machine learning can be used to provide the synthesis conditions and the stoichiometry of LMX compounds to maximize the gravimetric energy density of a battery cell.
