“…Furthermore, the Ragone plot of the staggered symmetrical supercapacitor based on the PSZT/ITO electrode is depicted to investigate energy density and power density during the charging/discharging process. As depicted in Figure 7c, the active polysiloxane film exhibits an approving power density of 3.75 kW kg −1 , which is better than some PANI-based all-solidstate supercapacitors, such as Zr-doped PANI composite (0.703 kW kg −1 ), 50 and Fe 3 O 4 -decorated rGO-doped PANI (0.55 kW kg −1 ). 51 Although the corresponding highest energy density of 7.2 Wh kg −1 is not outstanding for supercapacitive materials, it is comparable to some PANI-based all-solid-state supercapacitors, e.g., the CNT/PANI nanocomposite (7.1 Wh kg −1 ).…”

Electrochromic supercapacitors capable of indicating their energy levels by color changes have emerged as promising materials for use in a variety of next-generation devices and applications. However, a reflective indicating mode is less adventitious in applications and conditions with low ambient light, which inspires the exploration of emissive indicators. In this paper, we synthesized a network polysiloxane bearing fluorescence emissive cyanophenethylene groups and electroactive oligoaniline groups (PSZT) via an electrochemistry-assisted hydrolytic crosslinking reaction. The resulting PSZT exhibited high-performance electrochromic/electrofluorochromic behavior with a high optical contrast ratio (ΔT % of 52.5% varying from 71.0% to 18.5% at 700 nm), a marked fluorescence quenching ratio of 85%, and good switching durability. This PSZT was then incorporated into a smart symmetrical supercapacitor device integrating energy storage with the electrochromism/electrofluorochromism functions.Here, the energy status can be simultaneously indicated via tunable colors from transmissive green-yellow to dark green, along with a fluorescence on/off switch. This electrochromic/electrofluorochromic supercapacitor represents a direction toward smart energy storage systems.

“…It was realized that pseudoprotonation of PAni by Zr 4+ ions led to higher capacitance and intercalation of metallic ions into PAni layers. The energy and power density of the Zr‐doped PAni composite were observed to be 114.8 Whkg −1 at 2 mVs −1 scan rate and 703.5 Wkg −1 at 10 mVs −1 scan rate, respectively …”

With the ever-increasing depletion of nonrenewable fossil fuel reserve, greater attention has been directed towards renewable energy storage devices. One of the most important of such devices is the supercapacitor, which exhibits high specific capacitance. Polyaniline (PAni) is a versatile conducting polymer, which has demonstrated excellent electrochemical properties along with good stability and ease of synthesis.Therefore, PAni has been extensively used in the fabrication of supercapacitors. In the last few decades, researchers have studied the effect of morphology, developed during the synthesis of PAni, on its electrochemical properties. It is known that the electrical conductivity and the electrochemical properties of PAni get influenced by the level and type of dopant used, the method of synthesis adopted, and the surface area and porosity possessed. However, it has been realized that supercapacitors based on PAni suffer from short cycle life. This led to development of PAni composites with carbon-based materials and transition metal oxides. In this review, focus has been laid on the achieved performance levels of the recently developed PAni-based supercapacitors. In addition, an attempt has been made to study the fundamental aspects of the conductivity and the electrochemical properties of PAni and their effect on the supercapacitor performance. Moreover, several new interesting applications of PAni-based supercapacitors have also been included in this review.1 | INTRODUCTION Supercapacitors, for the last few decades, have accrued immense attention from the scientific society for their unique properties like long cycle life, wide operating temperature window, high power density, and fast charge-discharge cycle. 1,2 It can store charge in two different ways-either by electrostatic way (electrical double layer capacitors, EDLCs) or by thorough fast and reversible Faradaic reaction (pseudocapacitors). In case of EDLCs, the opposite charges are stored on the surface of the two parallel conductive plates with electrolytes between them that help in shuttling of ions between the two.EDLCs type of supercapacitors have shown higher power densities and hence higher rate capabilities. It has been studied that carbon-based materials have shown EDLC-type behavior with high power density, low cost, and tunable porosity but lacks in energy density. [3][4][5] Pseudocapacitors store charges through fast and reversible reaction, which can store charges near the surface of the electrode, and thus possess high capacitance but low power density. Transition metal oxides (TMOs), mixed TMOs, 6 and conducting polymers (CPs) exhibit pseudocapacitance. TMOs exhibit multiple oxidation states with low activation energy but lack high capacitance and flexibility and suffer from instability. In recent years, extensive studies have been done on TMOs and carbon-based materials. Another group of fascinating materials is CPs, which show high specific capacitance, flexibility, and ease of fabrication. The performance of the supercapacitor is...
