Abstract
The present invention relates to a method for manufacturing a cable-type secondary battery comprising an electrode that extends longitudinally in a parallel arrangement and that includes a current collector having a horizontal cross section of a predetermined shape and an active material layer formed on the current collector, and the electrode is formed by putting an electrode slurry including an active material, a polymer binder, and a solvent into an extruder, by extrusion-coating the electrode slurry on the current collector while continuously providing the current collector to the extruder, and by drying the current collector coated with the electrode slurry to form an active material layer.
