Abstract: The present invention relates to an anode for a secondary battery, comprising: a spiral anode having at least two anode wires which are parallel to each other and spirally twisted, each of the anode wires having an anode active material layer coated on the surface of a wire-type current collector; and a conductive layer formed to surround the spiral anode.The anode active material layer of the spirally-twisted has a thin thickness as compared with a single strand of an anode having the same anode active material. Therefore, Li ions can be easily diffused to enhance battery performance. Also, the anode of the present invention has a conductive layer on the surface thereof to prevent or alleviate the release of an anode active material which is caused by volume expansion during charging and discharging processes, and to solve the isolation of the anode active material.
