    Abstract: The present invention relates to an anode for a secondary battery, comprising: a wire-type current collector; a metal-based anode active material layer formed on the surface of the wire-type current collector, and comprising a metallic active material; and a graphite-based anode composite layer formed on the surface of the metal-based anode active material layer, and comprising a mixture of a graphite-based active material, a conductive material and a first polymer binder.The anode of the present invention has the metal-based anode active material layer together with the graphite-based anode composite layer acting as a buffer, thereby preventing the metallic active material from being isolated or released even if excessive volume expansion occurs during charging and discharging processes. Also, the graphite-based anode composite layer has good affinity with an organic electrolyte solution to compensate the defect of the metallic active material having low affinity with an organic electrolyte solution.
