Biomass-derived carbon materials offer a sustainable and low-cost platform for supercapacitor electrodes, yet their practical performance is often limited by low electrical conductivity, irregular pore structures, and restricted energy storage capability. This work addresses these challenges by modification of biomass-derived carbon with conducting polymers to form synergistic hybrid electrodes. The conducting polymers such as polypyrrole, polyaniline and poly(3,4-ethylenedioxythiophene) etc. coating enhances electron transport, introduces additional pseudocapacitance, and improves electrolyte ion accessibility, leading to significantly higher specific capacitance, better rate performance and energy density. The present study further explores synthesis strategies, structure–property relationships, and performance metrics in supercapacitors and related energy-storage systems, demonstrating how biomass-derived carbon can be useful for scalable future energy storage technologies.
