Abstract:
The present invention relates to an anode for a secondary battery, comprising 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 secondary battery comprising the anode. The anode of the present invention has an increased surface area to react with Li ions during a charging and discharging process, thereby improving the rate characteristics of a battery, and also release stress or pressure applied in the battery, e.g., the volume expansion of active material layers to prevent the deformation of the battery and ensure the stability thereof, thereby improving the life characteristic of the battery.
