Abstract
Provided is a method for manufacturing an anode of a cable-type secondary battery having a solid electrolyte layer, including preparing an aqueous solution of an anode active material, making an anode by immersing a core as a current collector having a horizontal cross section of a predetermined shape and extending longitudinally in the aqueous solution, then applying an electric current to form a porous shell of the anode active material on the surface of the core, and forming a solid electrolyte layer on the surface of the anode by passing the anode through a solid electrolyte solution. The anode has a high contact area to increase the mobility of lithium ions, thereby improving battery performance. Also, the anode is capable of relieving stress and pressure in the battery, such as volume expansion during charging and discharging, thereby preventing battery deformation and ensuring battery stability.
