A method of making an active material comprises the steps of forming a slurr y, spray drying the slurry to form a powdered precursor compositions, and heati ng the powdered precursor composition at a temperature and for a time sufficien t 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 compoun d, an insoluble carbonaceous material compound, or both. Electrodes and batteri es are provided that contain the active materials. |
