“…Ultrasonic exfoliation was suggested by C. Bathula et al A glass vial containing 50 mg of polymer PDT and 20 mL of toluene was stirred with an ultrasonic probe for 10 min to produce a fine solution. [39] The mixture was sonicated at 50 % amplitude for 1 hour to achieve PDPT-CNT. After sending CNTs in 5 mL of toluene at a concentration of 1 mg/mL.…”

Supercapacitors have emerged as a promising energy storage technology with attributes like high power and tuneable energy density along with splined cyclic potential. Their performance is heavily driven by the employed electrode materials that still crave high charge storage and rate capabilities as well as virile conductivity. Among numerous applied strategies to patch the corresponding quandary, sulfurization has garnered significant attention as an effective method for improving the electrochemical depiction of electrode materials. This review article presents a comprehensive analysis of the sulfurization process applied to the electrode with the aim of providing profound overview of the latest developments, the impact of sulfur incorporation on electrode properties, and the resulting performance enhancement in supercapacitors. It explores the influence of sulfidation on the morphological, structural, and compositional aspects of electrode materials, highlighting the modification of surface area, pore size distribution, crystal structure, and the formation of active sites. The discussions on the improved specific capacitance, enhanced rate capability, prolonged cycle life, and upgraded energy density achieved are accumulated. Additionally, the review explores the challenges and limitations associated with sulfurization and strategies to mitigate trials for future directions of research and developments.

The increasing demand for renewable energy sources worldwide and the predicted depletion of current fossil fuel sources need continuous energy storage and conversion technology development. The use of supercapacitors (SC) as electrical energy storage devices in consumer electronics items and alternative power sources is an interesting and potentially lucrative area of application. Therefore, continuous developments are conducted to improve SC performance using different composites and nanocomposites. Carbon materials in SC are among the most important uses of this material. This chapter provides a short communication on recent progress in supercapacitor-based carbon materials. Various fundamental carbon allotropes were presented and debated, including fullerene, carbon nanotubes, and graphene-based supercapacitors.

Summary Tremendous efforts have been made to create significant energy storage devices using nanoscale design and hybrid techniques. Toward this end, herein, we have fabricated, a binder‐free, amorphous iron‐doped nickel‐cobalt phosphate (FexNiCo(PO4)2, ie, F‐NCP) thin film on stainless steel substrate using a facile successive ionic layer adsorption and reaction (SILAR) method. Furthermore, the influence of Fe doping concentration on physico‐chemical properties is investigated. The various F‐NCP‐series electrodes contain nanoparticle‐like morphology that is beneficial for charge transfer and efficient diffusion of electrolytes in supercapacitors. Such nanoparticle‐like morphology and the synergy among iron, cobalt, and nickel elements in the F‐NCP‐3 electrode deliver a maximum specific capacity of 987 C g−1 at a current density of 2.1 A g−1 with excellent cyclic retention of 95.3% after 5000 galvanostatic charge‐discharge cycles. Especially, when an asymmetric solid‐state supercapacitor (ASSS) is fabricated in polyvinyl alcohol‐KOH gel electrolyte with reduced graphene oxide (rGO) as a negative electrode, the designed F‐NCP‐3//rGO ASSS device shows the wide (1.6 V) potential window, and a maximum specific capacitance of 116 F g−1 at 1.5 A g−1. In addition, the ASSS device gives a higher energy density of 41.26 Wh kg−1 at 1.22 kW kg−1 power density and exhibits superior cyclic stability (93% after 5000 cycles). The suggested asymmetric configuration makes a promising alternative of the cathode material to construct energy storage devices for various portable electronic systems.
