We provide in-depth insight into the electrochemical capacitive behaviour of multidimensional poly(3,4-ethylenedioxythiophene) (PEDOT) nanotubes (mPNTs) with unique surface substructures, such as nanonodules and nanorods (NR). NRs–mPNT had a capacitance of 153 F g-1 in acidic electrolyte. They showed a 17% increase in specific capacitance when coupled to another pseudocapacitive component, namely, manganese dioxide (MnO2). MnO2–mPNTs were further tested in both symmetric and asymmetric cell configurations without using binders or conductive fillers.The asymmetric MnO2–mPNTs (+)//RGO–CNFs ( ) cell exhibited better performances than other asymmetric or symmetric cells of the MnO2–mPNTs/RGO–CNFs combination in terms of specific capacitance, cycling stability, and coulombic efficiency. |
