Abstract:
Provided is a cathode active material including a complex coating layer, which includes M below, formed on a surface of the cathode active material through reaction of a lithium transition metal oxide represented by Formula 1 below with a coating precursor: Li x MO 2   (1) wherein M is represented by Mn a M′ 1-b , M′ is at least one selected from the group consisting of Al, Mg, Ni, Co, Cr, V, Fe, Cu, Zn, Ti and B, 0.95≤x≤1.5, and 0.5≤a≤1. The lithium secondary battery including the cathode active material exhibits improved lifespan and rate characteristics due to superior stability.

Claim (Index 2):
The cathode active material according to  claim 1 , wherein the complex coating layer is prepared by: mixing and reacting the lithium transition metal oxide with the first coating precursor and the second coating precursor, and\n wherein the lithium transition metal oxide is mixed with the first coating precursor and the second coating precursor in a dry method.
