NOVELTY - A cable-type secondary battery (300) consists of hollow core portion (310), inner electrode, separation layer (340), outer electrode and protection film (370), and has horizontal cross section, and is extended in longitudinal direction. The inner electrode is provided with inner electrode active material layer (330) formed on surface of inner current collector (320), which is formed by enclosing outer side of hollow core portion. The outer electrode is provided with outer current collector (360) formed by enclosing outer side of outer electrode active material layer (350).    USE - Cable-type secondary battery e.g. lead accumulator, nickel cadmium battery, nickel hydrogen storage battery, lithium ion battery and lithium ion polymer battery used for notebook, cellular phone and motor vehicle accessories.    ADVANTAGE - The cable-type secondary battery has stable interface between electrolyte and electrode, excellent performance characteristics, and suppressed leakage of electrolyte, and is safe.    DETAILED DESCRIPTION - A cable-type secondary battery consists of a hollow core portion, into which a gel polymer electrolyte is injected, an inner electrode, a separation layer, an outer electrode and a protection film, and has a horizontal cross section, and is extended in a longitudinal direction. The inner electrode is provided with an inner current collector formed by enclosing an outer side of the hollow core portion, and an inner electrode active material layer formed on surface of the inner current collector. The separation layer is formed by enclosing an outer side of the inner electrode. The outer electrode is provided with an outer electrode active material layer formed by enclosing an outer side of the separation layer, and an outer current collector formed by enclosing an outer side of the outer electrode active material layer. An INDEPENDENT CLAIM is included for manufacture of cable-type secondary battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the cable-type secondary battery.
