Claim:
1. A method for manufacturing an anode of a cable secondary battery having a solid electrolyte layer, the method comprising: preparing an aqueous solution of an anode active material; making an anode by immersing a current collector having a horizontal cross section of a predetermined shape and extending longitudinally in the aqueous solution, said current collector comprising a polymer core and a metal coating layer formed on a surface of the polymer core, then applying an electric current to form a porous shell of the anode active material on a surface of the current collector; and forming a solid electrolyte layer on a surface of the anode by passing the anode through a solid electrolyte solution, wherein pores of the porous shell are filled with a solid electrolyte, wherein the porous shell has a pore size of 10 to 150 μm, and wherein the porous shell has a porosity more than 60% and no more than 95%.
