Abstract

A cathode active material for a lithium secondary battery according to exemplary embodiments of the present invention includes a lithium metal oxide particle core part and an organic compound coating layer which includes a functional group containing a sulfur atom. The cathode active material may suppress side reactions with an electrolyte while maintaining the stability of the layered structure of the lithium metal oxide particles, suppress a gelation phenomenon of the slurry during manufacturing a cathode, and maintain the high energy, high output and long life-span characteristics of the lithium secondary battery.
