Abstract

Disclosed are a method of manufacturing a flexible thin-film type super-capacitor device and a super-capacitor device manufactured by the same. 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.

First claim

What is claimed is:

1. A sealing material comprising:
base members which comprise scaling portions for forming a space to accommodate a material therein and containing and sealing up the accommodated material;
a hot-melt adhesive which is coupled to one of the sealing portions; and
a sealing means which seals up the sealing portion in a state that the hot-melt adhesive is coupled to the sealing portion,
wherein the material accommodated in the space includes electrolyte having potassium hydroxide (KOH),
wherein the material of the hot-melt adhesive comprises paraffin that is primarily thermal-adhered to tightly prevent leakage of the electrolyte and polyolefin that is secondarily thermal-adhered so that adhesion between the base members can be maintained, and
wherein the base members and the hot-melt adhesive are coupled with each other so that the sealing material has flexibility.

2. The sealing material according to claim 1 , wherein the sealing means uses one of a press method, an adhesive adhesion method, a thermal adhesion method, a thermal fusion method and a welding method.

3. The sealing material according to claim 1 , wherein the hot-melt adhesive is arranged inside a certain width from an outmost edge of the base members.

4. The sealing material according to claim 1 , wherein
the sealing material for sealing up the electrolyte is provided in a capacitor.

5. The sealing material according to claim 1 , wherein the material of the hot-melt adhesive further includes ethylene vinyl acetate (EVA).

6. The sealing material according to claim 1 , wherein the base members include 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,
wherein the base members further include an active material, and
wherein the sealing material is used as a capacitor which comprises a current collector including an electrode electrically connected to the active material.

7. A sealing material comprising:
one base member and another base member each of which comprising sealing portions positioned at a certain width at outer edges of the one base member and the another base member, the sealing portions for forming a space to accommodate a material therein and containing and sealing up the accommodated material; and
a hot-melt adhesive which is coupled to one of the sealing portions so that the hot-melt adhesive is interposed between the one base member and the another base member,
wherein the material accommodated in the space includes electrolyte having potassium hydroxide (KOH), and
wherein the material of the hot-melt adhesive comprises either paraffin and polyolefin or paraffin and ethylene vinyl acetate (EVA).
