    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 and an open-structured outer current collector.
    The open-structured outer current collector according to the present invention has good flexibility and a certain degree of elasticity to improve the flexibility of a cable-type battery having the same, and can be less subjected to excessive deformation such as bending or severe folding, due to its structural characteristic, even if excessive external force is applied to the cable-type battery, thereby preventing a short circuit due to the contact with the inner current collector and the release of an active material. Also, the open-structured outer current collector can be present inside the outer electrode active material layer to improve an electric contact between the outer current collector and the outer electrode active material layer, thereby contributing to the enhancement of battery characteristics.
