Abstract
Disclosed is an anode for a lithium secondary battery. The anode includes a current collector in the form of a wire and a porous anode active material layer coated to surround the surface of the current collector. The three-dimensional porous structure of the active material layer increases the surface area of the anode. Accordingly, the mobility of lithium ions through the anode is improved, achieving superior battery performance. In addition, the porous structure allows the anode to relieve internal stress and pressure, such as swelling, occurring during charge and discharge of a battery, ensuring high stability of the battery while preventing deformation of the battery. These advantages make the anode suitable for use in a cable-type secondary battery. Further disclosed is a lithium secondary battery including the anode.
