Abstract:
A method for manufacturing an anode for a cable-type secondary battery, includes forming a lithium-containing electrode layer on the outer surface of a wire-type current collector; and surrounding the outer surface of the lithium-containing electrode layer with a substrate for forming a polymer layer spirally, and pressing the outside of the substrate for forming a polymer layer to form a polymer layer on the lithium-containing electrode layer, wherein the polymer layer includes a hydrophobic polymer, an ion conductive polymer, and a binder for binding the hydrophobic polymer and the ion conductive polymer with each other. An anode obtained from the method and a cable-type secondary battery including the anode are also provided.
