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 8):
