    摘要： Provided is an anode for a lithium secondary battery composed of a multi-layered structure including an electrode current collector, a first anode active material layer including a first anode active material formed on the electrode current collector, and a second anode active material layer including a second anode active material having relatively lower press density and relatively larger average particle diameter than the first anode active material.Since an anode according to an embodiment of the present invention may include a multi-layered active material layer including two kinds of anode active materials having different press densities and average particle diameters on an electrode current collector, porosity of the surface of the electrode may be improved even after a press process to improve ion mobility into the electrode. Thus, charge characteristics and cycle life of a lithium secondary battery may be improved.
