Abstract
Disclosed is a fabrication method for an electrode active material, and a lithium battery comprising an electrode active material fabricated therefrom. The fabrication method for an electrode active material comprises preparing an aqueous solution by dissolving a precursor that can simultaneously undergo positive ion substitution and surface-reforming processes in water; mixing and dissolving raw materials for an electrode active material with a composition ratio for a final electrode active material in the aqueous solution, thereby preparing a mixed solution; removing a solvent from the mixed solution, thereby forming a solid dry substance; thermal- processing the solid dry substance; and crushing the thermal-processed solid dry substance.
