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.
