Conducting Polymers Based Nanocomposites for Supercapacitors

Among the unconventional electrically powered devices (supercapacitors, batteries, and fuel cells), supercapacitors have received significant interest due to their better electrochemical performance, exceptional cycle life, outstanding specific power, and rapid charging/discharging rate. Furthermore, supercapacitors based on conducting polymers (CPs) have higher power density and specific energy, giving them a more versatile and less expensive energy storage option. CPs have been the subject of intensive research over the years due to their potential use in various disciplines such as sensors, fuel cells, and supercapacitors. Several novel techniques have been developed to enhance the characteristics of CPs, including CPs-based nanocomposites, which combine CPs with other nanomaterials. Due to their high capacitances and ability to endure multiple charge/discharge cycles, CPs-based nanocomposites have become more popular as supercapacitor electrodes. We summarize essential topics in this study field following a discussion of the obstacles that CPs-based nanocomposites must overcome to become technologically feasible. This chapter will help readers understand the benefits and drawbacks of using the CPs-based nanocomposites in supercapacitors and identify topics for further research.
