A cable-type secondary battery, includes an electrode assembly including first and second polarity electrodes with a thin and long shape, each electrode having a current collector whose cross-section perpendicular to its longitudinal direction is a circular, asymmetrical oval or polygonal shape, and an electrode active material applied onto the surface of the current collector, and a separator or an electrolyte layer interposed between the first and second polarity electrodes; and a cover member surrounding the electrode assembly. Also, the cable-type secondary battery is provided with a first polarity terminal and a second polarity terminal connected to the first polarity electrode and the second polarity electrode, respectively, at the end of the cable-type secondary battery; and a housing cap configured to fix the first and second polarity terminals and cover the end of the cable-type secondary battery. |
