Efficient ion transport in activated carbon capacitors assembled with gelled …

A B S T R A C T The beneficial feature of the polymeric framework in a gel electrolyte is to assist ion transport via the segmental motion of the polymer chains. This feature was displayed by ac impedance analysis on an activated carbon capacitor assembled with a gel electrolyte, which consisted of poly(ethylene oxide)-copoly(propylene oxide) as a host, propylene carbonate (PC) as a plastici…
