ABSTRACT:
A method of making a lithium manganese oxide intercalation compound in powder form comprises forming a solution of a manganese compound and a lithium compound in a solvent; and spray-drying the solution by atomizing the solution to form droplets thereof and contacting the droplets with a stream of non-oxidizing hot gas at a first elevated temperature to evaporate at least a major portion by weight of the solvent present in the solution thereby providing a precursor powder. The precursor powder is heated at a second elevated temperature which is below the melting point of the lithium manganese oxide compound. The second temperature is sufficient to cause reaction among constituents in the precursor powder thereby providing the lithium manganese oxide compound having a spinel unit structure.
