Abstract
Methods for synthesizing single 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.
