“…For example, Kim et al 147 synthesized a composite material containing PPy, vapor-grown carbon fibres, and carbon with a thickness of 5-10 nm by in situ chemical polymerization, and achieved specific capacitances of B588 and B550 F g Recently, the specific capacitance of an electrode modified with pure PANI was reported by Li et al to be 815 F g…”

“…147,[161][162][163] For example, the sulfonated multi-wall carbon nanotube (MWCNT) in the composites can greatly improve the cycle stability of PANI, only showing 5.4% loss from their initial specific capacitance after 1000 cycles. This was attributed to the use of MWCNT with exceptional mechanical properties as a support and the formation of the charge-transfer complex, which could reduce the cycle degradation problems of PANI caused by volume changes or mechanical problems.…”

Their advantages, disadvantages, and performance in ES electrodes are discussed through extensive analysis of the literature, and new trends in material development are also reviewed. Two important future research directions are indicated and summarized, based on results published in the literature: the development of composite and nanostructured ES materials to overcome the major challenge posed by the low energy density of ES (476 references).

“…As polymer films grow thicker, they tend to respond more slowly due to ion transport limitations, giving rise to lower capacities as well as energy and power densities. 6,18,64,65 Polymer nanostructures such as nanowires, nanotubes, or nanoparticles can help to alleviate problems associated with ion diffusion by increasing the surface area and porosity. …”

This review covers recent advances in conjugated polymers and their application in energy storage. Conjugated polymers are promising cost-effective, lightweight, and flexible electrode materials. The operating principles of conjugated polymers are presented within the framework of their potential for energy storage. Special focus is given to polyaniline electrodes. Recent advances are reviewed including new methods of synthesis, nanostructuring, and assembly. Also, covered are applications that take full advantage of the mechanical properties of conjugated polymers and future applications of these novel materials.

“…Also, on mixing 60 wt % of the PPy-VGCF with 25% of activated carbon (AC), the PPy-VGCF-AC composite electrode exhibited higher power capability, maintaining the specific capacitance per active material of PPy and AC as ∼300 F g −1 at 200 mV s −1 in 6 M of KOH. 55 In this work, electropolymerization of 1[4H-methoxyphenyl]-1H-pyrrole onto carbon fiber microelectrodes (CFMEs) and the effects of monomer concentration were reported. P(MPPy) thin films formed on CFMEs were characterized by scanning electron microscopy (SEM), atomic force microscopy Advances in Polymer Technology DOI 10.1002/adv (AFM), Fourier transform infrared reflectanceattenuated total reflection spectroscopy (FTIR-ATR), and electrochemical impedance spectroscopy (EIS).…”

In this study, films of poly[1-(4-methoxyphenyl)-1H-pyrrole][poly(MPPy)] were electrochemically grown on carbon fiber microelectrodes (CFMEs) in 0.05 M of tetraethyl ammonium perchlorate-dichloromethane. The effect of different monomer concentrations (range = 1-10 mM) on electrochemical properties of resulting polymers was characterized by cyclic voltammetry, Fourier transform infrared reflectance-attenuated total reflection spectroscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), and electrochemical impedance spectroscopy. All modified CFMEs were found to have capacitance on the basis of Nyquist, Bode-magnitude, Bode-phase, and Admittance plots. An equivalent circuit model of (R(C(R(QR)))(CR)) gave the best fit for all monomer
