“…The hydrothermal and the solvothermal methods involve confining the reactants in a reactor where the reaction process is accomplished by chemical transfer. 133 Liquid or gaseous water is the medium for transferring pressure at high temperatures and pressures, and most of the reactants can be partially dissolved in water, 134 allowing the reaction to take place at a critical level (coexistence of gas and liquid phases). 135 The hydrothermal method involves first mixing a certain proportion and concentration of a mixed metal salt solution and alkali solution quickly, 136 and then the mixture is immediately transferred to a stainless-steel high-pressure reaction kettle, where the reaction takes place at a certain temperature for 6–24 h, and finally after through washing, drying, grinding, powder products are obtained.…”

“…The sulfur species introduced during the process can chemically interact with the carbon framework, inhibiting the dissolution and diffusion of active materials during cycling, thereby mitigating capacity decay and extending the lifespan of the electrode. [76] Porous carbon possesses a tenable pore structure that can be further customized through sulfurization. Sulfur species can change the pore size distribution and introduce more mesopores or micropores, which can improve ion transport and electrolyte accessibility, eventually enhancing the electrochemical performance.…”

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.
