1. A method comprising:
making lithium nickel manganese cobalt oxide by
combining a molar excess of Li2O with a solid oxide precursor comprising NixMnyMzCo1-x-y-zO2;
heating the solid oxide precursor and the Li2O in an oxygen atmosphere at a first temperature T1 for a first effective period of time t1 to produce a first product;
cooling the first product; and
heating the first product in an oxygen atmosphere at a second temperature T2 for a second effective period of time t2 to produce lithium nickel manganese cobalt oxide having 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+1.0.
