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.
