发明名称 Cable-type secondary battery
摘要 The present disclosure provides a cable-type secondary battery, comprising: an inner electrode supporter; and a sheet-form laminate of inner electrode-separation layer-outer electrode, spirally wound on the outer surface of the inner electrode supporter, wherein the laminate of inner electrode-separation layer-outer electrode is formed by carrying out compression for the integration of an inner electrode, a separation layer for preventing a short circuit, and an outer electrode. In the cable-type secondary battery of the present disclosure, since the electrodes and the separation layer are adhered to each other and integrated, 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.

主权项 1. A cable-type secondary battery, comprising: an inner electrode supporter; and a sheet-form laminate of inner electrode-separation layer-outer electrode, helically wound on an outer surface of the inner electrode supporter, wherein the laminate of inner electrode-separation layer-outer electrode is formed by carrying out compression for the integration of an inner electrode, a separation layer for preventing a short circuit, and an outer electrode, wherein a peel strength between the inner electrode and the separation layer or between the separation layer and the outer electrode is 15 to 300 N/m.
