    摘要： Disclosed is a method for preparing a cathode active material for a lithium secondary battery, and the preparing method includes: adding a phosphorus compound to a transition metal oxide dispersion liquid to prepare a coating liquid; drying the coating liquid to prepare a powder including phosphorus oxide coated on the surface of the transition metal oxide; and dry-mixing the powder coated with the phosphorus oxide with a lithium intercalation compound, and then firing the mixture to form a solid solution compound of Li-M1-M2-P—O (where M1 is a transition metal derived from transition metal oxide, and M2 is a metal derived from lithium intercalation compound) on the surface of the lithium intercalation compound.The method for preparing a cathode active material for a lithium secondary battery simplifies the conventional preparing process to save process cost, and it provides comparable electrochemical characteristics to a cathode active material obtained from a wet process.
