Abstract

Supercapacitors are unconventional electrically powered devices that have attracted much attention because of their superior electrochemical performance, extraordinary cycle life, incredible specific power, and quick charging and discharging rates. Additionally, supercapacitors made from biomass-derived carbons (BDCs) and conducting polymers (CPs) have higher power densities and specific energies, making them a more adaptable and affordable energy storage solution. Due to their potential applications in various fields, including sensors, fuel cells, and supercapacitors, CPs have been the focus of extensive research over the years. This chapter focuses on engineering carbon-based composite electrodes using conducting polymers, particularly polyaniline and polypyrrole. Different synthesis methods for BDCs-CPs composites as electrode materials for supercapacitors are also discussed in detail and challenges and future perspectives are highlighted. This chapter will help readers to learn about the advantages and disadvantages of employing CPs-based composites in supercapacitors, and we suggest directions for future research.
