摘要： The present invention relates to a method for manufacturing a cable-type secondary battery, which includes 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, and which comprises electrodes extended in the longitudinal direction and disposed in parallel to each other. The manufacturing method for the electrode comprises the steps of: fabricating electrode slurry by injecting active material, a polymer binder, and a solvent into an extruder; extruding and coating the extrude slurry on the surface of a current collector while continuously supplying the current collector to the extruder; and drying the current collector on which the electrode slurry has been coated and thus forming an active material layer. Since the method for manufacturing a cable-type secondary battery using extrusion coating according to the present invention enables continuous coating of the electrode slurry on the current collector, the method is suitable for manufacturing a cable-type secondary battery extended in the longitudinal direction, and thus increases productivity. In addition, it is easy to adjust the thickness of a coating layer through adjustment of the conveying speed of a current collector or the extrusion speed of electrode slurry.

摘要： The present invention relates to a cable type rechargeable battery, and more particularly the cable type rechargeable battery of the present invention comprises: inner electrodes comprising at least two cathodes disposed in parallel, each of which has a horizontal cross section of a predetermined shape, extends in the length direction and has an electrolyte layer constituting a pathway for ions formed on the outer surface; an outer electrode constituting an anode, which comprises an anode active material layer that envelops the inner electrode; and a protective covering which is disposed around the outer electrode. The cable type rechargeable battery can freely change shape in that it has a linear structure while at the same time being flexible. The battery rating is high because a plurality of inner electrodes are provided inside the outer electrode which is shaped as a pipe, and hence the contact surface area is increased. Also, it is easy to adjust the capacity balance between the inner electrodes and the outer electrode by adjusting the number of inner electrodes, and short circuiting (shorting) can be prevented since the electrolyte layers are formed on the inner electrodes.
