Abstract: The present invention relates to a cable-type secondary battery which can be freely transformed, and more specifically, to a cable-type secondary battery having improved flexibility of the battery by preventing wrinkling, which may occur on a thin metal layer included in packaging. According to the present invention, the flexibility of an electrode can be drastically improved by introducing a support layer on at least one surface of a sheet-type external electrode, and the flexibility of the battery can be improved by forming the support layer, which is the outermost layer of the external electrode, and a polymer resin layer inside the packaging from the same material, and by preventing winkling on the thin metal layer included in the packaging by mutually coupling the support layer and the polymer resin layer.

Abstract: The present disclosure provides a cable-type secondary battery, comprising: an inner electrode; and a sheet-form laminate of separation layer-outer electrode, spirally wound to surround the outer surface of the inner electrode, the laminate being formed by carrying out compression for the integration of a separation layer for preventing a short circuit, and an outer electrode.According to the present disclosure, the electrodes and the separation layer are compressed and integrated to minimize ununiform spaces between the separation layer and the outer electrode and reduce the thickness of a battery to be prepared, thereby decreasing resistance and improving ionic conductivity within the battery. Also, the separation layer coming into contact with the electrodes absorbs an electrolyte solution to induce the uniform supply of the electrolyte solution into the outer electrode active material layer, thereby enhancing the stability and performances of the cable-type secondary battery.
