Nano-structured polyaniline (PANI) containing composite electrodes based on
Busofit T-040 carbon cloth (CC) with high specific surface area have been developed for
symmetric supercapaitor devices by one-step chemical polymerization of aniline. The
capacitive performance of the CC as well as the PANI/CC composites was characterized by
the cyclic voltammetry (CV) and the galvanostatic charge-discharge in H2SO4-based aqueous
electrolyte. A PANI/CC composite demonstrates significant capacitance enhancement up to
222 F g-1 and 6,7 F cm-2 (vs. 120 F g-1 and 3,1 F cm-2 for CC).
The coulomb efficiency of the
composites has been measured to be about 97-99 %. The technological simplicity, easy to
scale up and the electrochemical performance of the flexible binder-free PANI/CC electrodes
demonstrate the significance of this work for industrial application.
Keywords: Nano-structured polyaniline; carbon cloth.
