NOVELTY - The electrode has a support layer (30) inserted with a porosity layer. An electrode active material layer (20) is formed in a side of a current collector i.e. mesh-type current collector (10). A carbon nano tube is filled with metal powder. Conducting polymer and non-conducting polymer surfaces are treated with a conductive material i.e. aluminum - cadmium alloy. A stainless steel surface-is treated with carbon, stainless steel, aluminum, nickel, titanium, burning carbon, copper, nickel, titanium, silver and indium tin oxide. A primer coating layer is formed with the material and a binder.    USE - Electrode for a secondary battery e.g. stacked-type secondary battery, rolled-up-type secondary battery, stack / folding-type secondary battery, cable-type secondary battery and sheet-type secondary battery (all claimed) of a hybrid vehicle and an electric vehicle.    ADVANTAGE - The flexibility of the electrode is improved by introducing the support layer in a side of the sheet-like electrode so as to prevent crack generation of the electrode active material layer, avoid binder content increase of the electrode active material layer, prevent the electrode active material layer from being carried off in the current collector, prevent reduction of capacity of the battery, improve service life of the battery, smoothly facilitate electrolyte inflow to the electrode active material layer and prevent increase of resistance within the battery and performance degradation of the battery.    DETAILED DESCRIPTION - The current collector is formed with carbon paste that is provided with carbon-powder i.e. graphite. The metal powder is nickel, aluminum, silver, gold, palladium, chromium, tantalum, copper and barium. The binder is made of polyvinylidene fluoride, polyvinylidene fluoride - hexafluoro lochia propylene, polyvinylidene fluoride - trichloroethylene, polybutylacrylate, polymethyl methacrylate, poly acrylonitrile, polyvinyl pyrrolidone, polyvinylacetate, ethylene-vinyl acetate copolymer, polyethylene oxide, polyarylate, cellulose acetate, cellulose acetate butylate, cellulose acetate propionate, cyanoethyl pullulan, cyanoethyl polyvinyl alcohol, cyanoethylcellulose, cyanoethyl sucrose, pullulan, carboxyl methylcellulose, styrene butadiene rubber, acrylonitrile styrene butadiene copolymer and polyimide. The support 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, polyimide, polyether-ether-ketone, polyethersulfone, polyphenylene oxide, polyphenylenesulfide and polyethylene naphthalate. INDEPENDENT CLAIMS are also included for the following:    (1) a secondary battery electrode manufacturing method    (2) a cable-type secondary battery.
