“…To overcome these limitations, a recent presents a novel one-step sulfurization method for the direct fabrication of Ni 3 S 2 nanowires on a Ni foam substrate using a hydrothermal method. [68] SEM image depicts the morphologies of NiO/NF and Ni3S2/NF electrodes. Post-sulfidation, Ni3S2 nanowires uniformly disperse on NF, forming a secure anchor to NF network.…”

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.

“…15 However, the poor cycling stability is a major bottleneck for Ni systems due to aggregation in longer cycles. Especially, nickel based sulfides (Ni x S y ), 16,17 selenides (Ni x Se y ), 18,19 phosphides (Ni x P y ), 20,21 phosphates (Ni x (PO 4 ) y ), 22 etc. delivered promising capacitance but suffer from poor cycling stability.…”

Supercapatteries are contemporary electrochemical energy‐storage devices that bridge the gap between the conventional supercapacitors and rechargeable batteries. Supercapatteries utilize battery‐type electrode‐active materials for their charge storage. Among the various futuristic materials, transition‐metal dichalcogenides receive prominent attention due to their excellent charge‐storage capabilities. Herein, the microwave‐assisted hydrothermal synthesis of layered two‐dimensional (2D) nickel sulfide nanosheets (NSN) and their application as electrode‐active materials in high‐performance asymmetric supercapatteries are reported. The layered 2D architecture is preferred for the electrode‐active materials as the layered electrode nanostructure provides a hindrance‐free movement to the electrolyte ions through it during the charge‐storage process that include intercalation/deintercalation mechanisms. The electrochemical thermal stability of the 2D NSN electrode reveals that its stability in KOH (aqueous) electrolyte is better than that in LiOH (aqueous) and NaOH (aqueous) electrolytes. The supercapattery electrode synthesized using 2D NSN exhibits excellent electrochemical charge‐storage performances bearing a maximum specific capacity of 594.77 C g−1 (an equivalent mass‐specific capacitance of 991.29 F g−1) in 2 M KOH (aqueous) electrolyte. The electrochemical cycling performance of the 2D NSN electrode shows a stability over 40 000 cycles without any significant capacity loss. An asymmetric supercapattery device fabricated with 2D NSN electrode as positrode and activated carbon as negatrode exhibits a maximum mass‐specific capacity of 143.58 C g−1 with a corresponding energy density of 29.91 Wh kg−1 in 2 M KOH (aqueous) electrolyte.
