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 1):
A lithium secondary battery, comprising:\n 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, wherein the first cathode active material particle includes a lithium metal oxide including a continuous concentration gradient in at least one region between a central point and an outermost surface, wherein the first cathode active material particle contains nickel (Ni) and at least one metal except for lithium and nickel, and a molar ratio or a concentration of Ni is 0.7 or more throughout an entire region of the first cathode active material particle, wherein 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 portion, and the second cathode active material particle includes an excess amount of nickel among the metals except for lithium.
