摘要： An aqueous electric double layer capacitor having excellent wettability with aqueous electrolytic solution, low internal resistance, excellent easiness of forming uniform, thin and wide films and mechanical strength. Activated carbon powder, a polymeric binder having a hydrophilic group and a plasticizer are fully mixed to form a film which is then dried to form an electrode. By using a polymer having a hydrophilic group as a binder, wettability between an aqueous electrolytic solution and the electrode is improved and contact resistance between an electrolysis solution and the electrode can be reduced. In addition, by adding a plasticizer, the amount of polymer binder required to form a thin type electrode can be reduced, thus providing an aqueous solution electric double layer capacitor with low internal resistance.
