ABSTRACT
During the last few years, rigorous research work has been dedicated to conducting polymers (CPs) and their nanocomposites because they have wide applications in various disciplines, such as in research on fuel cells, sensors, and supercapacitors. Supercapacitors are one of the most important candidates for fulfilling almost all requirements for human sustainable growth because of their high energy storage capacity, large capacitance, high capability rate with long life cycle, and low-cost. Moreover, in supercapacitor application, CPs reveal great potential because of exceptional properties, including easy synthesis process, good conductivity, excellent flexibility, etc. To achieve outstanding electrochemical performance, several new approaches have been established to improve the properties of electrodes used for supercapacitors that consist of a combination of conducting polymers and nanoparticles. In this chapter, topical research development in supercapacitor application using CPs such as polyaniline, polypyrrole, and poly(3,4-ethylenedioxythiophene) has been reviewed and summarized. Also, this chapter focuses on study and development on CP-based binary and ternary composite electrodes for supercapacitor application. The future progress of CP-based supercapacitors is briefly discussed in the conclusion.
