Modification of the oxygen-containing functional group on activated carbon fiber in electrodes of an electric double-layer capacitor

<br/><br/> In order to discuss quantitatively the effect of functional groups of activated carbon fibers (ACFs)on electric double-layer characteristics, ACFs with various amounts of functional groups were prepared from the same ACF by redox methods. The amount of functional groups of ACFs was compared between the method by back titration and by X-ray photoelectron spectroscopy (XPS). In the case of the aqueous electrolyte, the electric capacity depended more on oxygen functional groups than on BET surface area. At the greatest 30
