Abstract
Methods of making such compounds, powders, and cathode active materials are described. The powders are formed of particles with specific properties: a particle size distribution with a D50 ranging from 10 μm to 20 μm, a D10 less than 8 μm, and a D99 of the particles ranges from 25 μm to 35 μm. The final compound is represented by the Formula Li(CoMnMeAl)O, wherein 0.95<α<1.05, x≤1.00, 0<y≤0.04, 0<z≤0.050, and δ≈2.
