Conductive Polymer and Composites for Supercapacitor Applications

Abstract

After the addition of dopants, conducting polymers with their own electrical conductivity were created. In addition to a polymer backbone, they also have a system of conjugated bonds. As a result of the conjugation, the polymers may now move electrons both along and across their chains (interchain hopping). Doping (of both p- and n-type) with acids and other substances produce conductivity. Both chemical and electrochemical approaches might be used to accomplish doping. The use of conducting polymer in electrochemical performances may be traced back to this finding. Doping can be accomplished by the application of voltage (in the form of electrons or holes). The charge may be stored and the capacitor's defining double layer can develop. Moreover, charging and discharging may take place over a broad range of voltages, making them a promising option for energy storage in conjunction with power plants. Several methods, including electrochemical and chemical oxidation, have been used to oxidize the conducting monomer. When it comes to electrode material for supercapacitors or batteries, polyaniline is one of the most researched and commonly used conducting polymers. This chapter delves further into the topic of supercapacitor composites based on polymer electrolytes. Energy storage systems like supercapacitors and lithium and other ion batteries were analysed for their software development and fundamental design constraints, as well as their limitations and future and present possibilities for enhancing energy storage technology. The goal of this Chapter is to make it easier to collect and analyze data on this polymer, which should open up new avenues of inquiry.
