Redox-active electrolyte for carbon nanotube-based electric double layer capa…

a b s t r a c t The specific capacitance of the MWCNTs was improved by the addition of an electrochemically active compound (indigo carmine) to an electrolyte generally used in electric double layer capacitors. The pseudocapacitive contribution of the IC trebled the specific capacitance values of the MWCNTs at low current densities (from 17 Fg−1 to 50 Fg−1). The good resistance obtained f…
