Cable-type secondary battery

A cable-type secondary battery comprising:

• at least one cathode extending longitudinally and having a horizontal cross section of a predetermined shape;
• a first electrolyte layer surrounding the cathode and serving as an ion channel;
• at least one anode extending longitudinally and having a horizontal cross section of a predetermined shape, the anode and the cathode arranged in parallel;
• a second electrolyte layer serving as an ion channel commonly surrounding and contacting the anode and the first electrolyte layer;
• and
• a protection coating surrounding the second electrolyte layer,
• wherein the anode includes a anode current collector and an anode active material layer formed on the outer surface of the anode current collector,
• wherein the cathode includes a cathode current collector and a cathode active material layer formed on the outside of the cathode current collector.
