Abstract
The present invention relates to a cable-type secondary battery comprising an inner electrode comprising at least two anodes arranged in parallel, the anode extending longitudinally and having a horizontal cross section of a predetermined shape, the anode having an electrolyte layer thereon serving as an ion channel; an outer electrode comprising a cathode including a cathode active material layer surrounding the inner electrode; and a protection coating surrounding the outer electrode. The cable-type secondary battery has free shape adaptation due to its linearity and flexibility. A plurality of inner electrodes within a tubular outer electrode lead to an increased contact area therebetween and consequently a high battery rate. It is easy to control the capacity balance between the inner and outer electrodes by adjusting the number of inner electrodes. A short circuit is prevented due to the electrolyte layer formed on the inner electrode.
