NOVELTY - The electrode has a supporting layer (40) formed in an upper part of a porous polymer layer (30) that is made of inorganic particle or binder polymer material. An organic and inorganic porous layer is laminated in an upper part of an electrode active material layer (20) that is coated in a side of a mesh-type current collector (10). The collector is made of graphite, metal paste, carbon black or carbon nanotube. Metal powder is coated on the collector. A primer coating layer is provided with conductive material and binder. The polymer layer is mixed with polarity and oxide chain polymers.    USE - Electrode for use in a sheet-shaped secondary battery and a cable-type secondary battery (all claimed) e.g. nickel-cadmium battery, nickel-hydrogen storage battery, lithium-ion battery and lithium-ion polymer battery, that is utilized in a handheld device, an uninterruptible power supply system and vehicle such as electric vehicle and hybrid vehicle i.e. car (all claimed).    ADVANTAGE - The electrode active material layer is coated in the side of the mesh-type current collector and the supporting layer is formed in the upper part of the organic and inorganic porous layer that is laminated in the upper part of the electrode active material layer so as to avoid crack generated on the electrode active material layer and deformation of the mesh-type outside current collector, thus improving connectivity, power storage capacity, flexibility and durability of the electrode. The smooth inflow of electrolyte into the electrode active material layer can be facilitated through the supporting layer. The resistance increased within the electrode can be prevented so as to enhance operating performance of a sheet-shaped secondary battery.    DETAILED DESCRIPTION - The metal powder is selected from nickel, aluminum, gold, silver, palladium, chromium, tantalum, copper or barium. The supporting layer is a mesh-type porous film or nonwoven fabric. The supporting layer is made of high-density polyethylene, low-density polyethylene, linear low-density polyethylene, ultrahigh molecular weight polyethylene, polypropylene polyethylene terephthalate, polybutylene terephthalate, polyester, polyacetal, polyamide, polycarbonate, polyether-ether-ketone, polyethersulfone, polyphenylene oxide, polyphenylenesulfide or polyethylene naphthalate.
