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 1):
A cathode active material comprising a complex coating layer, over a surface of a lithium transition metal oxide represented by Formula (1):\n Li x MO 2 \u2003\u2003(1) wherein M represents Mn a M\u2032 1-b , wherein M\u2032 is at least one selected from Al, Mg, Ni, Co, Cr, V, Fe, Cu, Zn, Ti or B, wherein 0.95\u2264x\u22641.5, 0.5\u2264a\u22641, and b=a+x\u22121, wherein the complex coating layer has at least one combination structure selected from Li-M-X, Li-M-m or Li-M-X-m, wherein X is a halogen element derived from a first coating precursor, wherein m is a metal element derived from a second coating precursor, and wherein the first coating precursor is an organic compound comprising a halogen element, X, and X is F, Cl, Br or I, and the second coating precursor is an oxide comprising a metal, m, and the metal, m, is at least one selected from the group consisting of Al, Ba, Ca, Mg, Si, Ti, Zr, Zn, and Sr derived from the oxide.
