Cathode for Lithium Secondary Battery and Lithium Secondary Battery Including the Same

A cathode for a lithium secondary battery, comprising:

• a cathode current collector;
• a first cathode active material layer on the cathode current collector, the first cathode active material layer comprising first cathode active material particles and a first binder, the first cathode active material particles comprising large-scaled particles having an average diameter (D50) from 10 μm to 20 μm and small-scaled particles having an average diameter from 1 μm to 9 μm;
• and
• a second cathode active material layer on the first cathode active material layer, the second cathode active material layer comprising second cathode active material particles having an average diameter (D50) from 1 μm to 20 μm and a second binder,
• wherein a content of the large-scaled particles based on a total weight of the first cathode active material particles is in a range from 50 wt % to 80 wt %, and a content of the small-scaled particles based on a total weight of the first cathode active material particles is in a range from 20 wt % to 50 wt, and
• a content of the second binder based on a total weight of the second cathode active material layer is less than or equal to a content of the first binder based on a total weight of the first cathode active material layer, and the content of the second binder is less than 1 wt %.
