Provided are a cathode active material composition, a cathode plate, a secondary battery, a battery module, a battery pack, and an electric device. In particular, the present application provides a cathode active material composition, including a cathode active material and a dispersant. The cathode active material composition of the present application can improve the poor dispersion of the cathode active material powder and the high viscosity of the slurry during the preparation of the cathode slurry, and further improve flexibility of the cathode plate.
