  "textContent": "A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer comprising a first cathode active material layer and a second cathode active material layer sequentially stacked on the cathode current collector. The first cathode active material layer includes first cathode active material particles having a secondary particle structure, and the second cathode active material layer includes second cathode active material particles having a single particle shape. A ratio of a SPAN value of the second cathode active material particles relative to a SPAN value of the first cathode active material particles is in a range from 2 to 4.5.",
