In the present invention, the positive electrode collector; A cathode active material layer; And a primer layer formed between the cathode current collector and the cathode active material layer, wherein the primer layer includes lithium carbonate (Li 2 CO 3 ) particles having two or more kinds of particle diameters, a binder polymer, and a conductive material A positive electrode for a lithium secondary battery and a lithium secondary battery including the same are provided. In the overcharged state, the lithium secondary battery quickly reaches the overcharge end voltage due to the gas generated between the positive electrode current collector and the positive electrode active material layer, so that the safety of the lithium secondary battery can be secured. |
