Original Abstract Submitted
A cathode for a lithium secondary battery includes a cathode current collector, a first cathode active material layer on the cathode current collector and a second cathode active material layer on the first cathode active material layer. The first cathode active material layer includes first cathode active material particles and a first binder. The first cathode active material particles include large-scaled particles having an average diameter (D50) from 10 μm to 20 μm and small-scaled particles having an average (D50) diameter from 1 μm to 9 μm. The second cathode active material layer includes second cathode active material particles having an average diameter (D50) from 1 μm to 20 μm and a second binder.
