CATHODE ACTIVE MATERIAL AND METHOD FOR PREPARING SAME

A method for manufacturing a cathode active material comprises: preparing a cathode active material precursor; setting the temperature in heat treatment equipment to a target firing temperature; and firing the cathode active material precursor, a lithium salt, and a dopant material at the target firing temperature using the heat treatment equipment to manufacture the cathode active material, wherein the target firing temperature is controlled according to the dopant material. The setting the temperature in the heat treatment equipment to a target firing temperature includes: obtaining the difference value between a set firing temperature of the heat treatment equipment and the actual firing temperature in the heat treatment equipment; constructing a DB on the basis of the difference value; and using the DB to set the set firing temperature of the heat treatment equipment so that the target firing temperature matches the actual firing temperature in the heat treatment equipment.
