Abstract:
A process for producing an electric double layer capacitor comprising an electrode containing a carbonaceous material having a specific surface area of at least 500 m2/g, and an organic electrolytic solution in interfacing contact with the electrode, the electrolytic solution being capable of forming an electric double layer at the interface with the electrode, which comprises.kneading a mixture of the carbonaceous material and a fluorine-containing resin; forming the mixed material into a shape of a sheet to prepare an electrode sheet; coating a conductive adhesive containing a conductive carbon material and a polyimide resin onto a current collector; pasting the electrode sheet on the coated surface of the current collector; and then drying by heating the current collector at a temperature of at least 200Â° C.
