“…All of the samples exhibit extraordinary redox peaks, indicating that the electrodes behave like batteries. The intense interaction between OH ions and the electrode surface is largely responsible for the prominence of these redox peaks [43,47]. The increasing area under the CV curves in both dimensions reflects the rapid reactions occurring at the electrolyte-electrode interface [48].…”

Conducting polymers have attained a lot of interest due to extraordinary conductivity, large pore size, and surprising stability. In this work, the conducting polymer polyaniline (PANI) and niobium sulfide (NbS) were synthesized by polymerization of aniline and hydrothermal method, respectively. The PANI@NbS nanocomposite electrode material had a specific capacity (Cs) of 1050 C g−1, which is larger than that of the reference sample (NbS = 300 C g−1). Besides, the hybrid device (PANI@NbS//PANI@AC) was designed and the electrochemical characteristics were determined. The hybrid device showed an excellent value of Cs of 1207 C g−1 with higher energy density Ed and power density Pd. The device also exhibited remarkable stability, and 85 % of the initial capacity is retained after 1000 cycles.

The efficient and sustainable use of energy is highly imperative to satisfy the escalating energy demands arising from the rapid commercialization of technologies. The development of novel electrochemical energy technologies is an essential aspect in the present-day scenario of rapid depletion of existing sources of energy. Conducting polymers are promising psuedocapacitive materials with an extended delocalisation network of  electrons, flexibility to functional modifications and facile intercalation and de-intercalation of electrolyte ions. These factors enable them to possess capacitances comparable with those of metal oxides. The use of copolymers in this context is noteworthy due to their diversity of combining different types of monomer units and facile integration. Carbon based materials have also been extensively employed on account of their high power densities and large number of charge-discharge cycles. The synergism of the non-faradaic double-layer capacitance with the faradaic charge transfer has the ability to provide impressive supercapacitor properties. Different types of polymer and polymer-composites based supercapacitors have been discussed with special emphasis on implantable biomedical devices and wearable electronics.
