Summary: | A cathode for a lithium secondary battery includes a cathode current collector, a first cathode active material layer including a first cathode active material particle, and a second cathode active material layer including a second cathode active material particle. The first cathode active material layer and the second cathode active material layer are sequentially stacked from the cathode current collector. The first cathode active material particle and the second cathode active material particle have different compositions or particle structures from each other. The first cathode active material particle and the second cathode active material particle include lithium metal oxides containing nickel. The second cathode active material particle has a single particle shape and has a particle size distribution satisfying a specific range relation. |
