Abstract

In this study, we investigate the frequency response of microsupercapacitors based on pseudocapacitive conducting polymer electrodes such as poly(3,4-ethylenedioxythiophene) (PEDOT), polypyrrole (PPY) and polyaniline (PANI). It is shown that by proper choice of polymeric material and device structure, mainiturized microsupercapacitors based on electroactive polymers can match the frequency response of commercial bulky electrolytic capacitors. Specifically, we shsow that PEDOT-based microsupercapacitors exhibit phase angle of -80.5º at 120 Hz which is comparable to commercial bulky electrolytic capacitors, but with an order of magnitude higher capacitance density (3 FV/cm3). The trade-off between the areal capacitance (CA) and frequency response in the 2D architecture (CA = 0.3 mF/cm2, phase angle of -80.5º at 120 Hz) is improved by designing 3D thin film architecture (CA = 3 mF/cm2, phase angle of -60º at 120 Hz). Our work demonstrates that fast frequency response can be achieved using electroactive polymer electrodes.
