Method of synthesizing electrochemically active materials from a slurry of precursors

Abstract From the Canadian patent

A method of making an active material comprises the steps of forming a slurry spray drying the slurry to form a powdered precursor compositions and heating , the powdered precursor composition at a temperature and for a time sufficient to form a reaction product. The slurry has a liquid phase and a solid phase and contains at least an alkali metal compound and a transition metal compound. Preferably the liquid phase contains dissolved alkali metal compound, and the solid phase contains an insoluble transition metal compound an insoluble carbonaceous material compound or both. Electrodes and batteries , are provided that contain the active materials.
