The present invention provides a method of manufacturing a cable-type secondary battery comprising a current collector having a horizontal cross-section of a predetermined shape and an active material layer formed on the surface of the current collector, the electrode extending in a longitudinal direction and arranged in parallel. Preparing an electrode slurry by injecting an active material, a polymer binder, and a solvent into an extruder; Extruding and coating an electrode slurry on the surface of the current collector while continuously supplying the current collector to the extruder; And drying the current collector coated with the electrode slurry to form an active material layer. Since the method of manufacturing a cable-type secondary battery using the extrusion coating of the present invention enables continuous coating of the electrode slurry on the current collector, it is suitable for the production of the cable-type secondary battery extending in the longitudinal direction, thereby increasing productivity. In addition, it is easy to control the thickness of the coating layer by adjusting the extrusion speed of the current collector to the electrode slurry. |
