摘要： Disclosed is a cathode current collector for an electrical energy storage device and a method for manufacturing the same, which improves adhesion between a current collector and an electrode material and provide a high reaction surface area, thereby improving the performance of the electrical energy storage. In particular, a first alumina film is formed on the surface of an aluminum foil using an anodic oxidation process. Next, the first alumina film formed on a surface of the aluminum foil is removed through etching and a second alumina film is formed on the surface of the aluminum foil, from which the first alumina film is removed, using the anodic oxidation process again. Subsequently, a carbon layer is coated on a surface of the aluminum foil on which the second alumina film is formed.

摘要： 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.
