The flexible thin-film type super-capacitor device comprises a base film which has flexibility; a separator which is interposed between the base films; and an active material which is formed on the base film. Thus, flexibility is given since thickness is very thin while maintaining high electrical conductivity and high binding property. In addition, economic feasibility is high and mass production is possible. Further, it is possible to stably and efficiently contain a highly corrosive material. ## Claims ### Claim 1 A method of manufacturing a capacitor device, the method comprising: preparing a base film that has flexibility; forming an active material on the base film; and coupling base films comprising active materials with a separator therebetween so that the active materials can face each other, wherein the forming the active material comprises using graphene oxide, and the active material is generated by making slurry of graphene oxide be heated, exposed to light and thermally treated. ### Claim 2 (depends on 1) The method according to claim 1, wherein the base film comprises a polyphenylene sulfide (PPS) film, a polypropylene (PP) film, a polyethylene phthalate (PET) film, a polycarbonate (PC) film, a polyethylene naphthalate (PEN) film, a polyethylene terephthalate (PET) film and a film on which metal comprising aluminum is deposited, and the base film undergoes surface treatment. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: forming a current collector on each base film between the base film and the separation membrane, wherein the current collector is formed by plating, and the plating comprises electroless plating or electric plating, and wherein the plating solution comprises one selected from a group consisting of nickel (Ni), platinum (Pt), silver (Ag), gold (Au), copper (Cu), aluminum (Al), palladium (Pd) and iridium (Ir). ### Claim 4 (depends on 3) The method according to claim 3, wherein in the forming the current collector, the base film comprises a polyphenylene sulfide (PPS) film, and a surface of the base film to be plated is made rough, sensitized, activated, put into electroless nickel plating solution and then plated. ### Claim 5 (depends on 3) The method according to claim 3, wherein in the forming the current collector, the base film comprises a polypropylene (PP) film, and a surface of the base film to be plated is etched, catalyst particles are attached to the surface of the base film and activated, and nickel plating is performed. ### Claim 6 (depends on 1) The method according to claim 1, further comprising: performing vacuum-impregnation so that the electrolyte can be infiltrated into the active materials. ### Claim 7 A method of manufacturing a capacitor device, the method comprising: preparing a base film that has flexibility; forming a current collector on the base film; forming an active material with graphene oxide on the current collector; coupling base films comprising current collectors and active materials with a separator therebetween so that the active materials can face each other; and coupling a hot-melt adhesive film for sealing up around the base film to maintain air-tightness of an electrolyte provided between the active materials, wherein the electrolyte is highly corrosive, and the hot-melt adhesive film comprises a plastic paraffin film and a polyolefin film. ### Claim 8 (depends on 7) The method according to claim 7, further comprising reinforcing materials coupled to the backs of the hot-melt adhesive films and thermally adhered to each other. ### Claim 9 (depends on 8) The method according to claim 8, wherein the hot-melt adhesive film and the reinforcing material are adhered by one or a plurality of methods selected among a method of using an adhesive, a thermal adhesion method, a thermal fusion method and a welding method.
