NOVELTY - The battery (100) has an inner electrode (120) provided with an inner current collector that is connected with an outer surface of a lithium-ion supply core portion (110). An active material layer is formed at a surface of the inner current collector. An electrolyte absorbing layer is formed at an outer surface of the active material layer. A separation layer (130) is formed at an outer surface of the inner electrode. An outer electrode is fixed with an outer surface of the separation layer and arranged with an outer electrode active material layer (140) and an outer current collector (150).    USE - Cable-type secondary battery for use in a hybrid vehicle and an electric vehicle. Uses include but are not limited to a lead accumulator, a nickel cadmium battery, a nickel-hydrogen storage battery, a lithium ion battery and a lithium ion polymer battery.    ADVANTAGE - The battery is filled with an electrolyte at the lithium-ion supply core portion, and penetrates the lithium-ion supply core portion to the outer electrode active material layer so as to perform supplying and exchanging of lithium ion in an easier manner. The battery is prevented from being damaged. The battery has better capability, cycle-ability and flexibility.    DETAILED DESCRIPTION - The inner current collector is adhered with stainless steel, carbon, aluminum, nickel, titanium, burning carbon, copper, nickel, titanium, silver, aluminum-cadmium alloy, conductive material and conductivity polymer. The conductive material is a mixture of polyacetylene, polyaniline, polypyrrole, polythiophene, polysulfur nitride, indum thin oxide, silver, palladium and nickel. The conductivity polymer is a mixture of polyacetylene, polyaniline, polypyrrole, polythiophene and polysulfur nitride. The electrolyte absorbing layer is made of gel-type polymer electrolyte, polyvinylidene fluoride (PVdF), PVdF-hexafluoropropene (HFP), polymethyl methacrylate (PMMA), polyvinyl acetate, polypropylene oxide, polyethylene imine, polyethylene sulphide and polyvinyl acetate, and contains lithium salt.
