Abstract: The present disclosure relates to a positive electrode for a secondary battery. According to the present disclosure, when manufacturing a positive electrode having the same thickness, it is possible to make the binder distribution uniform in the thickness direction of the electrode active material layer by using a dual layer coating process, and to provide an effect of improving binding force by allowing the binder resin of the lower layer portion of the positive electrode active material layer to be retained in the lower layer portion. In addition, it is possible to improve the electrochemical characteristics of a battery by using a different composition of positive electrode material in the upper layer portion and the lower layer portion of the positive electrode, particularly, by introducing a sacrificial positive electrode material merely to the lower layer portion.
