Abstract
A process of manufacturing a positive active material for a lithium secondary battery includes preparing a coating-element-containing organic suspension by adding a coating-element source to an organic solvent, adding water to the suspension to prepare a coating liquid, coating a positive active material with the coating liquid, and drying the coated positive active material.
