Electric double layer capacitor and method for manufacturing the same

摘要

An electric double layer capacitor having increased electrode density and decreased resistance and a method for manufacture the same are disclosed. A binder comprising butadiene-styrene, carboxymethyl cellulose, and polytetrafluoroethylene is prepared and mixed with activated carbon powder and carbon black to obtain a slurry mixture. The mixture is then coated on a charge collecting body to form an electrode and subjected to a pressing process to obtain a resulting electric double layer capacitor having 20% increased electrode density and 50% reduced resistance.
