ヒドロキノン／繊維状活性炭電極の電気二重層‐擬似容量複合キャパシタへの応用

Abstract

Hydroquinone is known to show an oxidation-reduction reaction. Active carbon felt with adsorbed hydroquinone shows higher capacitance than normal activated carbon does. Adsorbed hydroquinone shows a rapid oxidation-reduction reaction that can match a capacitor’s rapid charge and discharge. Furthermore, active carbon felt with adsorbed hydroquinone has longer-term stability than normal active carbon felt has, as demonstrated using cyclic voltammetry and constant current electrolysis.
