Abstract
Provided is a cable-type secondary battery including an electrode assembly having a horizontal cross section of a predetermined shape and extending longitudinally, and a wire-type outer current collector wound on the outer surface of the electrode assembly, the electrode assembly including an inner current collector, an anode active material layer, and an electrolyte layer, and a cathode active material layer; the wire-type outer current collector has excellent flexibility and a predetermined level of elasticity, and thus, improves the flexibility of the entire cable-type secondary battery and prevents a short circuit from occurring and the active material from falling off from the active material layer, due to the deformation of the cable-type secondary battery.
