A method for manufacturing a positive active material is provided. The method includes forming a positive active material precursor including nickel, mixing and firing the positive active material precursor and lithium salt to form a preliminary positive active material particle, forming a coating material including fluorine on the preliminary positive active material particle by dry-mixing the preliminary positive active material particle with a coating source including fluorine, and manufacturing a positive active material particle by thermally treating the preliminary positive active material particle on which the coating material is formed.

Cathode active material, method for manufacturing same, and lithium secondary battery comprising same

A positive active material is provided. The positive active material may include lithium, an additive metal, and at least one of nickel, cobalt, manganese, or aluminum. The additive metal may include an element different from nickel, cobalt, manganese, and aluminum. An average content of the additive metal may be less than 2 mol %.
