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 Liα(Co1-x-y-zMnxMezAly)Oδ, wherein 0.95

Abstract: The disclosed embodiments relate to the manufacture of a precursor co-precipitate material for a cathode active material composition. During manufacture of the precursor co-precipitate material, an aqueous solution containing at least one of a manganese sulfate and a cobalt sulfate is formed. Next, a NH4OH solution is added to the aqueous solution to form a particulate solution comprising irregular secondary particles of the precursor co-precipitate material. A constant pH in the range of 10-12 is also maintained in the particulate solution by adding a basic solution to the particulate solution.
