Fabrication of Electropolymerized Binder-Free Flexible Electrode of PANI-Fe-Doped <i>Borassus flabellifer</i> <i>-</i>Biomass-Derived (0D)-Carbon Quantum Dots for High-Performance Asymmetric Supercapacitors.

ABSTRACT: The rapid evolution of energy storage technologies demands electrode materials that deliver a high energy density, flexibility, and long-term stability. In this work, a binder-free, flexible supercapacitor electrode was fabricated via electro-polymerization of polyaniline (PANI) doped with Fe ions and carbon quantum dots (CQD). The novelty of this study lies in the first-time use of biomass-derived CQDs from Borassus flabellifer, which exhibit a strong natural affinity toward Fe³⁺ ions, enabling uniform incorporation into the PANI matrix during electro-polymerization. This unique design integrates three complementary charge-storage mechanisms by high conductivity from the PANI backbone, reversible Fe³⁺ redox activity, and EDLC-type capacitance from the CQD, alo
