“…As shown in Figure 3a, four elements of C, N, O and Ni are observed in the NPG composites. Figure 3b shows the C 1s XPS spectra, it can be seen that three peaks at 284.8, 286.8 and 289.1 eV are observed, which correspond to the C=C bond (sp 2 hybridized carbons), C−N bond (PANI) and C−O bond (the oxygen‐containing functional groups in rGO), respectively [49,50] . In N1s spectra (Figure 3c), three peaks at 399.4, 400.7 and 401.9 eV are observed, which can be ascribed to =N− (quinonoid amine), −NH− (benzenoid amine) and N + (nitrogen cationic amine), respectively [51] .…”

A facile and environmentally friendly one‐step electrodeposition method is developed to prepare Ni(OH)2/PANI/rGO (NPG) composites. The structure and morphology characterization of NPG composites reveal that Ni(OH)2 and PANI grow uniformly on the rGO layers surface, which makes the composites have large specific surface area (118.3 m2 g−1) and better electrochemical properties. The specific capacitance value of NPG composites reaches to 2320 F g−1 and 1746 F g−1 at a current density of 5 A g−1 and 20 A g−1, respectively, indicating that NPG ternary composites has excellent rate performance. Moreover, cycle stability, another very important performance indicator of supercapacitors, is also further investigated. When the NPG composites is charged and discharged after 2000 cycles at a current density of 10 A g−1, the capacitance retention remains 84.39 %. Furthermore, the NPG||activated carbon asymmetric supercapacitor shows a high energy density of 96.5 Wh kg−1 at a power density of 465.6 W kg−1. All the electrochemical properties demonstrate that NPG composites have great potential applications in electrode materials of supercapacitors.

“…Among them, the soft template method is considered to be a well‐suited synthesis method to synthesize PANI with controlled morphology and excellent electrochemical properties. Several different types of organic sulfonic acids are used as surfactant‐based soft templates as well as dopants to grow PANI nanostructures for improved electrochemical properties 21‐23 . In this method, strong wander wall forces, hydrogen bonding and other driving forces act on the supermolecules to self‐assemble themselves in the desired morphology 23,24 .…”

Summary In this study, we followed a facile method to grow well‐aligned PANI nanostructures on S‐doped reduced graphene oxide nanosheets (SPANI/S‐rGO) using hydrothermal method combined with soft template polymerization of aniline where naphthalene sulfonic acid is used as a dopant for PANI as well as the soft template. The effect of using different wt% of S‐rGO on the structural, morphology, and electrochemical performance of SPANI/S‐rGO composites has been evaluated. Supercapacitor fabricated using SPANI/S‐rGO10 (10 wt% of S‐rGO) composite based electrodes delivered a high specific capacitance of 347.5 F/g at a current density of 1 A/g in symmetrical cell design (the specific capacitance was calculated based on a single electrode). Only 11% of its initial capacitance is lost after 2500 cycles at a current density of 2 A/g. The enhanced performance is attributed to the optimum loading of S‐rGO in designing binary composite, well‐aligned growth of SPANI nanostructures on S‐rGO sheets, and synergistic effect of both S‐rGO and SPANI. The facile synthesized SPANI/S‐rGO composite electrode material with the aforementioned features is considered to be a promising candidate for a high‐performance supercapacitor.

“…Traditionally available activated carbons, prepared from precursors of coals like peat, lignite, and bituminous, are relatively high cost. Thus, obtaining porous carbons from bio‐waste is a cost‐effective approach for synthesizing porous activated carbons 8‐10 . Therefore, it is essential to find suitable biowaste‐derived carbons that retain activated carbons' properties.…”

Summary Carbon and metal oxide nanocomposites have been extensively studied as electrode materials to develop energy and power‐dense supercapacitors in recent years. Nevertheless, nano carbons with improved porosity and functional moieties are the most eco‐friendly and cost‐effective supercapacitor materials. In this work, carbon nano‐onions (CNOs) synthesized by a single‐step flame soot collection method, subsequently calcined at 600°C in an inert environment (CNO‐600), are used as electrode material for the supercapacitors. CNO‐600 s have a layer‐by‐layer nano onion structure with a ~25 nm particle size and a Brunauer–Emmett–Teller surface area of 147 m2 g−1. CNO‐600 delivers 266 and 186 F g−1 of capacitance at 0.5 A g−1 for half cells and symmetric ultracapacitors, respectively. Ultracapacitors show capacitance retention of 91% with 20 000 GCD cycles in 1 M H2SO4 electrolyte. The stable capacitance of CNO‐600 is due to easy intercalation/de‐intercalation of electrolyte ions and electrons in the layer‐by‐layer structure of CNOs, contributing to pseudocapacitive charge storage with electric double layer capacitor behavior. The lead‐carbon hybrid ultracapacitor fabricated using CNO‐600 as anode material and PbO2 as cathode delivers a specific capacitance of 515 F g−1 at 1 A g−1 in 4.5 M H2SO4 electrolyte in the voltage range of 2.3 and 0.6 V. The substantial improvement of charge storage in CNO‐based symmetric and lead‐carbon hybrid system, demonstrate an excellent opportunity for the development of high‐performance supercapacitors.
