PROBLEM TO BE SOLVED: To extremely reduce the moisture in electrodes to hardly cause the performance deterioration by constituting an adhesive layer by curing a conductive adhesive contg. a conductive powder, epoxy resin, curing agent and solvent of a specified b. p. or less. SOLUTION: Ethanol is added to and kneaded with a mixture of coconut husk active C powder, polytetrafluoroethylene and C black, the mixture is sheeted and roll-rolled to form an electrode sheet, an electrode sheet of about 40 mm square is cut from this sheet, adhered and fixed through a conductive adhesive to the surface of a etched Al foil collector and heated at a reduced pressure, 150 deg.C or above to do the dry treatment. The conductive adhesive is prepared by mixing a conductive C black powder, bisphenol A type epoxy resin, curing agent of diethylene triamine and solvent of e.g. methyl ethyl ketone of a b. p. of 160 deg.C or less. |
