“…The area specific capacitance is calculated to be 800 mF cm −2 at a current density of 1 mA cm −2 , based on the equation: = ×Δ /(Δ × ), where (mF cm −2 ) is the area specific capacitance, and Δ are the charge/discharge current density and time, respectively, Δ is the potential window, and is the projected area of the electrode. This remarkable area capacitance is comparable to those negative electrodes reported previously, such as WO 3 @PPy (253 mF cm −2 ) and PEDOT/SDS-GO composite (79.6 mF cm −2 ) [26,32]. The capacitance retained about 98.8%, 81.6% and 66.7% of its initial value at 1 mA cm −2 when charged/discharged at 2.5, 5, and 7.5 mA cm −2 , respectively, showing that the ANW electrode has good rate capability.…”

WO3nanowires directly grown on graphene sheets have been fabricated by using a seed-mediated hydrothermal method. The morphologies and electrochemical performance of WO3films prepared by different process were studied. The results show that the precoated nanoseeds and graphene sheets on graphite electrode provide more reactive centers for the nucleation and formation of uniform WO3nanowires. The WO3nanowires electrode exhibits a high area specific capacitance of 800 mF cm−2over negative potential range from −1.0 V to 0 V versus SCE in 1 M Li2SO4solution. A high performance electrochemical supercapacitor assembled with WO3nanowires as negative electrode and PANI/MnO2as positive electrodes over voltage range of 1.6 V displays a high volumetric capacitance of 2.5 F cm−3, which indicate great potential applications of WO3nanowires on graphene sheets as negative electrode for energy storage devices.

“…Fundamentally, supercapacitors can be classified into two main groups based on their energy charge storage mechanism, that is, electrical double layer capacitors (EDLC) and pseudocapacitors. In an EDLC with carbon-based materials as an electrode material, the energy storage is derived electrostatically from the charging process [3]. In contrast, pseudocapacitor uses conducting polymers (CP) or metal oxides as electrode materials stores charge via reversible Faradic reaction [4].…”

A comparative study of multiwalled carbon nanotube (MWCNT), graphene oxide (GO), and nanocrystalline cellulose (NCC) as a dopant in the preparation of poly(3,4-ethylenedioxythiophene)- (PEDOT-) based hybrid nanocomposites was presented here. The hybrid nanocomposites were prepared via the electrochemical method in aqueous solution. The FTIR and Raman spectra confirmed the successful incorporation of dopants (MWCNT, GO, and NCC) into PEDOT matrix in the process of formation of the hybrid nanocomposites. It was observed that the choice of the carbon material affected the morphologies and supercapacitive properties of the hybrid nanocomposites. Incorporation of GO with PEDOT produces a paper-like sheet nanocomposite in which the wrinkled surface results in larger surface area compared to the network-like and rod-like structures of PEDOT/MWCNT and PEDOT/NCC, respectively. Owing to larger surface area, PEDOT/GO exhibits the highest specific capacitance (120.13 F/g), low equivalent series resistance (34.44 Ω), and retaining 87.99% of the initial specific capacitance after 1000 cycles, signifying a long-term cycling stability. Furthermore, the high performance of PEDOT/GO is also demonstrated by its high specific energy and specific power.

“…In the case of PProDOT/YRFC and PProDOT/SRFC composites, only the diffraction peaks of the PProDOT was appeared. Additionally, the peak attributed to carbon spheres within composites almost disappears, manifesting that the YRFC and SRFC are completely covered by the PProDOT and the scattered PProDOT particles in the composites increase the distance between the carbon spheres . With the successful formation of PProDOT/YRFC and PProDOT/SRFC composites, the characteristic diffraction peaks of PProDOT are relatively enhanced.…”

In this article, the yolk–shell structure of resin‐based carbon spheres (YRFC) and the solid structure of resin‐based carbon spheres (SRFC) were prepared by condensation polymerization, and then novel spherical composites of poly(3,4‐propylenedioxythiophene)/YRFC (PProDOT/YRFC) and PProDOT/SRFC were obtained by in situ chemical oxidative polymerization. The prepared composites were characterized by Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible absorption spectra (UV–vis), Raman, X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET), X‐ray photoelectron spectrometer (XPS), scanning electron microscope (SEM), and transmission electron microscopy (TEM). Electrochemical behavior of the composites were investigated with reference to their suitability as electrode materials in electrochemical capacitors (ECs), which were accomplished by a combination of cyclic voltammetry and galvanostatic charge/discharge cycles. The resultant PProDOT/YRFC composite showed ideal charge storage capacity with a specific capacitance of 327.5 F g−1 at the current density of 1 A g−1, which is much higher than that of the materials of PProDOT/SRFC (298.1 F g−1) and PProDOT (180.9 F g−1). Furthermore, long cycle life was achieved with the optimized PProDOT/YRFC and the capacitance retention is 87.3% after 10,000 charge/discharge processes, which was attributed to its uniformly dispersible fluffy structure.
