MANUFACTURING METHOD OF CATHOD ACTIVE MATERIAL FOR LITHIUM RECHARGEABLE BATTERY AND CATHOD ACTIVE MATERIAL MADE BY THE SAME

摘要

The present invention relates to a method for manufacturing a cathode active material for a lithium secondary battery, and a lithium secondary battery manufactured using the method. In a method for manufacturing a cathode active material for a lithium secondary battery according to the present invention, a heat treatment temperature is adjusted according to a concentration of a transition metal having a concentration gradient, thereby manufacturing a cathode active material having improved stability and capacity.
