Abstract
The present disclosure provides a cable-type secondary battery which includes: at least one inner electrode; a separation layer formed to surround the outer surface of the inner electrode and configured to prevent a short of the electrodes; a sheet-type outer electrode surrounding the separation layer or the inner electrode and formed by spiral winding; and a polymer electrolyte coating layer formed to surround the sheet-type outer electrode, wherein the sheet-type outer electrode is formed by spiral winding to avoid an overlap.
