PURPOSE: A method for fabricating an electric double layer capacitor of a thin film type is provided to improve an electrochemical characteristic by forming an electrode including PVdF(polyvinylidenefluoride) and PVP(polyvinylpyrrolidone). CONSTITUTION: An electric double layer capacitor(100) of a thin film type is formed with an activated carbon electrode(10), an electrolyte(20), a collector(30), and a separator(40). The activated carbon electrode(10) is used for storing charges by using activated carbon. The electrode(10) is formed with a porous structure. The electrolyte(20) is formed with organic solvent, ammonium salt, and sulfuric acid. The conductivity of the electrolyte(20) can be improved by using propylene carbonate, ethylmethyl carbonate, and a mixture of propylene carbonate and ethylmethyl carbonate. The separator(40) is formed with non-woven fabric, porous polyethylene, and a polypropylene film. |
