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 separation layer interposed between the cathode and the anode. The first cathode active material particle includes a lithium metal oxide in which at least one metal forms a concentration gradient. The second cathode active material particle includes primary particles having different shapes or crystalline structures from each other.
