Abstract: A cable type secondary battery includes an inner electrode support; and a sheet-like inner electrode-separation layer-outer electrode complex which is spirally wound around the outer side of the inner electrode support. The inner electrode-separation layer-outer electrode complex is formed such that an inner electrode, a separation layer, and an outer electrode are compressed integrally. According to one embodiment, an electrode and a separation layer are bonded integrally so that the separation layer in close contact with the electrode absorbs electrolyte so as to induce a uniform supply of the electrolyte to an outer electrode active material layer, thereby increasing the stability and performance of a cable type secondary battery. In addition, the cable type secondary battery has a sheet-like electrode, whereby the resistance of the cable type secondary battery is reduced and the performance of the battery may be improved.

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.
