PROBLEM TO BE SOLVED: To attain improvement in capacity without damaging the characteristics of polytetrafluoroethylene as an adhesive agent at electrode foil production for an electric double-layer capacitor. SOLUTION: A polymer of at least one kind of butyl rubber (IIR), polyvinylidene fluoride(PVDF), ethylene propylene diene rubber(EPDM), natural rubber(NR), nitryl rubber(NBR), polyethylene(PE), polypropylene(PP), silicone rubber, vinyl acetate having lipophilicity or hydrophilicity higher than that of polytetrafluoroethylene(PTFE) is added to PTFE, and the wetness of activated carbon and electrolyte in the electrode is improved. Thus, the electric double- layer capacitor which improves capacity and lowering resistance is provided, while effectively utilizing the surface area of the activated carbon. |
