Abstract:
A lithium secondary battery includes a cathode formed from a cathode active material including a first cathode active material particle and a second cathode active material particle, an anode and a separator interposed between the cathode and the anode. The first cathode active material particle includes a lithium metal oxide including a continuous concentration gradient in at least one region between a central portion and a surface portion. The second cathode active material particle includes a lithium metal oxide including at least two metals except for lithium which have constant concentrations from a central portion to a surface, and the second cathode active material particle includes an excess amount of nickel among the metals except for lithium.

Claim (Index 2):
The lithium secondary battery according to  claim 1 , wherein the first cathode active material particle includes the lithium metal oxide represented by Chemical Formula 1:\n Li x M1 a M2 b M3 c O y \u2003\u2003[Chemical Formula 1] wherein, in the Chemical Formula 1 above, M1 is Ni, and M2 and M3 are selected from Co, Mn, Na, Mg, Ca, Ti, V, Cr, Cu, Zn, Ge, Sr, Ag, Ba, Zr, Nb, Mo, Al, Ga or B, and 0.7\u2264a\u22640.9 and 0.1\u2264b+c\u22640.3.
