| 发明名称 | Cable-type secondary battery | ||
| 摘要 | The present invention relates to a cable-type secondary battery having a horizontal cross section of a predetermined shape and extending longitudinally, comprising: an inner electrode having an inner current collector and an inner electrode active material layer surrounding the outer surface of the inner current collector; a separation layer surrounding the outer surface of the inner electrode to prevent a short circuit between electrodes; and an outer electrode surrounding the outer surface of the separation layer, and having an outer electrode active material layer, an open-structured outer current collector and a conductive paste layer.;The outer electrode having a conductive paste layer and an open-structured outer current collector according to the present invention has good flexibility to improve the flexibility of a cable-type secondary battery having the same. Also, the conductive paste layer is made of a light material, and thus can contribute to the lightening of the cable-type secondary battery. | ||
