“…Plasma-based polymerization techniques are promising methods for fabricating PANI/CNT nanocomposites. Hussain et al [82] used a radio frequency plasma-enhanced chemical vapor deposition method to synthesize vertically aligned CNTs on a TiN/SiO 2 /Si substrate using a Ni catalyst. As shown in Figure 6a, the prepared CNTs were vertically aligned (2 μm in length).…”

Polyaniline has been widely used in high-performance pseudocapacitors, due to its low cost, easy synthesis, and high theoretical specific capacitance. However, the poor mechanical properties of polyaniline restrict its further development. Compared with polyaniline, functionalized carbon materials have excellent physical and chemical properties, such as porous structures, excellent specific surface area, good conductivity, and accessibility to active sites. However, it should not be neglected that the specific capacity of carbon materials is usually unsatisfactory. There is an effective strategy to combine carbon materials with polyaniline by a hybridization approach to achieve a positive synergistic effect. After that, the energy storage performance of carbon/polyaniline hybridization material has been significantly improved, making it a promising and important electrode material for supercapacitors. To date, significant progress has been made in the synthesis of various carbon/polyaniline binary composite electrode materials. In this review, the corresponding properties and applications of polyaniline and carbon hybrid materials in the energy storage field are briefly reviewed. According to the classification of different types of functionalized carbon materials, this article focuses on the recent progress in carbon/polyaniline hybrid materials, and further analyzes their corresponding properties to provide guidance for the design, synthesis, and component optimization for high-performance supercapacitors.

“…Carbon is unique in the sense that a simple change in its local environment leads to a variety of different nanostructures that have substantially advanced the field of carbon science. [ 1–6 ] sp 2 carbons (structurally ordered or disordered) are very attractive in numerous domains particularly the ones devoted to energy conversion and storage. The involved sp 2 carbons are derived from the thermal conversion [ 7–9 ] of organic precursors (solid, liquid or gas).…”

The Raman spectra of graphene‐based matter exhibit a set of defect/disorder‐induced bands. The D band, which exhibits a strong dispersion up to ~50 cm−1/eV, comes from transverse optical phonons around K or K′ in the first Brillouin zone and involves an intervalley double resonance (DR) Raman process. In the present work, resonant Raman scattering (lines ranging from 1.58 to 3.81 eV) is used to study the unusual behavior of the one‐phonon Raman band of a carbonaceous material (anthracene‐based carbon which is one of the graphitizable carbons) upon its secondary carbonization stage (450°C–1000°C). While the G band appears to be nondispersive, the D band exhibits a change in both position and intensity. Its dispersion progressively rises from ~6 cm−1/eV to values close to what is usually observed in defected graphene‐based systems when anthracene‐based carbon becomes almost pure. This evolution appears to be correlated with a release of hydrogen (fixed on the edges of polyaromatic layers) questioning their role in changing the D band resonance conditions.

“…Supercapacitor has received much attention in recent years owing to its short charge/discharge time, high power density, good cycle stability, low maintenance cost and environmental friendliness [1][2][3]. Many electrode materials including metal oxides/hydroxides [5,6], metal sulfides [7], conductive polymers [8,9] and carbon materials [4] have been investigated for the supercapacitors. Among them, the carbon materials exhibit low specific capacitances.…”

CuCo2S4 is regarded as a promising electrode material for supercapacitor, but has inferior conductivity and poor cycle stability which restrict its wide-range applications. In this work, hierarchically hybrid composite of CuCo2S4/carbon nanotubes (CNTs) was synthesized using a facile hydrothermal and sulfuration process. The embedded CNTs in the CuCo2S4 matrix provided numerous effective paths for electron transfer and ion diffusion, and thus promoted the faradaic reactions of the CuCo2S4 electrode in the energy storage processes. The CuCo2S4/CNTs-3.2% electrode exhibited a significantly increased specific capacitance of 557.5 F g-1 compared with those of the pristine CuCo2S4 electrode (373.4 F g-1) and CuO/Co3O4/CNTs-3.2% electrode (356.5 F g-1) at a current density of 1 A g-1. An asymmetric supercapacitor (ASC) was assembled using the CuCo2S4/CNTs-3.2% as the positive electrode and the active carbon as the negative electrode, which exhibited an energy density of 23.2 Wh kg-1 at a power density of 402.7 W kg-1. Moreover, the residual specific capacitance of this ASC device retained 85.7 % of its original value after tested for 10000 cycles, indicating its excellent cycle stability.
