Abstract In this study, Fe‐doped polyaniline/dye‐functional composite modified carbon felt electrode was synthesized using hydrothermal method and a supercapacitor exhibiting 1.5 V obtained with 3.0 M KCl aqueous electrolyte. order to improve performance easily effectively, the effect of Lanaset Green B (LGB) acidic dye concentration on in polyaniline polymerization investigated. Electrochemical, morphological structural characterizations electrodes (CFt/Fe‐PANI/LGB) were carried out. The results showed that capacitance increases due strong interaction functional groups between PANI molecules improves properties pseudocapacitive supercapacitors by providing potential redox materials. CFt/Fe‐PANI/LGB(3 mM) displayed high specific 1543 F g −1 at scan rate 5 mV s half‐cell system. full‐cell, assembled symmetric has maximum energy density 32.7 Wh kg power 1250 W . display retention performances 82.3 % 78.8 after 2400 5000 cycles electrolyte, respectively. mM), flexible, wearable material improved behavior polymer play an important role for textile electronics applications.

As worldwide energy consumption continues to increase, so too does the demand for improved storage technologies. Supercapacitors are devices that receiving considerable interest due their appealing features such as high power densities and much longer cycle lives than batteries. such, supercapacitors fill gaps between conventional capacitors batteries, which characterised by density density, respectively. Carbon nanomaterials, graphene nanoplatelets, being widely explored supercapacitor electrode materials surface area, low toxicity, ability tune properties desired application. In this review, we first briefly introduce theoretical background basic working principles of then discuss effects material selection structure carbon nanomaterials on performances supercapacitors. Finally, highlight recent advances nanoplatelets how chemical functionalisation can affect improve performance.
