Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

A method of mixing a cathode active material in a process of manufacturing a cathode of a lithium secondary battery is provided. The method includes a preparation step of preparing a lithium compound removal solution in which PAA (polyacrylic acid) is mixed with a solvent, a removal step of reacting the lithium compound removal solution with the cathode active material, on a surface of which a lithium compound is present, thus removing the lithium compound present on the surface of the cathode active material, and a mixing step of mixing the cathode active material, which is mixed with the lithium compound removal solution, with a conductive material and a binder.
