The present invention relates to a positive electrode active material for a lithium secondary battery, a method for producing the same, and a lithium secondary battery including the same, which can reversibly intercalate and deintercalate lithium. And a coating layer containing M formed on the surface of the compound, wherein M is at least one selected from the group consisting of Al, Zr, Ti, Mg, V, Zn, Mo, Ni, Co, and Mn. Wherein the surface free energy of the cathode active material is 4 to 20% less than the surface free energy of the compound capable of reversible intercalation and deintercalation of the lithium. can do. |
