“…Figure 3b–d in the Nyquist plots of the MN, AN, and WN composites shows a typical supercapacitive form. [ 26 ] The high‐frequency area displayed an arc in composites MN, AN, and WN. The straight lines of the composites from microalgae (MN) and asphaltene (AN) slanted more toward the y ‐axis than those from WN composite, exhibiting unusual electrochemical behavior.…”

This study describes the creation and use of composites of nickel oxide and activated carbon as supercapacitor electrodes. A one-pot reaction is used to synthesize composite materials of nickel oxide and activated carbon (microalgae, asphaltene, and wood). A precursor solution of Ni(OH) 2 is blended with activated carbon through a precipitating method at a controlled weight ratio of nickel oxide and activated carbon, then the obtained powder is calcinated at 300 C for 3 hr. The composites are analyzed by X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray analysis (EDX). It is confirmed that nickel oxide sprouted on activated carbon surface. At a nickel oxide activated carbon weight ratio of 1:20, the greatest specific capacitances at 1 A/g current density are 624.2, 487.1, and 403 F/g, respectively.

“…Poly (2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) and ammonium molybdate [(NH 4 ) 2 MoO 4 ] (Mo) composite demonstrated an effective supercapactive performance when it is in a redox-mediated environment [77]. Conducting polymers are always combined with other compounds to form complete and compensated properties such as the polyelectrolyte additions; for example, the zwitterionic silica sulfobetaine [78]. This helps to enhance the capacitive performance.…”

Smart hydrogels with high electrical conductivity, which can be a real source of power while also collecting and storing the diverse sources of energy with ultrahigh stretchability, strong self-healability, low-temperature tolerance, and excellent mechanical properties, are great value for tailored wearable cloths. Considerable effort has been dedicated in both scientific and technological developments of electroconductive hydrogels for supercapacitor applications in the past few decades. The key to realize those functionalities depends on the processing of hydrogels with desirable electrochemical properties. The various hydrogel materials with such properties are now emerging and investigated by various scholars. The last decade has witnessed the development of high-performance supercapacitors using hydrogels. Here, in this review, the current status of different hydrogels for the production of flexible supercapacitors has been discussed. The electrochemical properties such as capacitance, energy density and cycling ability has been given attention. Diverse hydrogels, with their composites such as carbon-based hydrogels, cellulose-based hydrogels, conductive-polymer-based hydrogels and other hydrogels with excellent electromechanical properties are summarized. One could argue that hydrogels have played a central, starring role for the assembly of flexible supercapacitors for energy storage applications. This work stresses the importance of producing flexible supercapacitors for wearable clothing applications and the current challenges of hydrogel-based supercapacitors. The results of the review depicted that hydrogels are the next materials for the production of the flexible supercapacitor in a more sustainable way.

“…Recently, our previous works have shown that SPB plays an essential role in the synthesis of conductive nanocomposites for application in printed electronics due to its brush-like conformation [18,19]. However, there are few reports on the hydrothermal modification of carbon spheres by using poly (sodium 2-acrylamido-2-methylpropane-1-sulfonate) which has been widely used in supercapacitors [20] and drug release [21].…”

The paper reports a facile synthesis of novel anionic spherical polymer brushes which was based on grafting sodium 2-acrylamido-2-methylpropane-1-sulfonate from the surface of 4,4′-Azobis (4-cyanopentanoyl chloride)-modified carbon spheres. Various characterization methods involving a scanning electron microscope, energy dispersive X-ray spectroscopy, Fourier transform infrared spectrum, and thermo-gravimetric analysis were utilized to analyze the morphology, chemical composition, bonding structure, and thermal stability, respectively. The molecular weight (Mw) and polydispersity (Mw/Mn) of brushes were 616,000 g/mol and 1.72 determined by gel permeation chromatography experiments. Moreover, the dispersibility of ASPB in water and in the presence of aqueous NaCl solutions of different concentrations was investigated. Results show that the dispersibility of carbon spheres has been enhanced owing to grafted polyelectrolyte chains, while the zeta potential of the particle decreases and its brush layer shrinks upon exposure to sodium ions (Na+).
