Scalable synthesis strategies for MOS ₂ : a systematic review for high-performance supercapacitor applications

Abstract To meet the escalating demands for efficient energy storage, researchers are turning their attention to the cutting-edge electrode materials, and molybdenum disulfide, or MoS 2 , is fast emerging as a top contender for Supercapacitor application. SCs are renowned for their rapid charge-discharge properties and high-power density, and as such their performance is heavily dependent on the electrochemical properties of their electrodes. The highly ordered, 2D structure and redox favorable properties of the transition metal dichalcogenides, and specifically MoS 2 , made them stand out from other materials. Nonetheless, there was no easy method of manufacturing high-quality MoS 2 , that could reliably scale up production, and yet be economical. Exfoliation, hydrothermal synthesis, chemical vapour deposition, microwave-assisted synthesis, and electrochemical methods were the several methods investigated. Hydrothermal synthesis turned out to be the winner, mainly because it is straightforward, inexpensive, and allows for MoS 2 to be produced with the desired electrochemical properties. In this review, the authors go in-depth into how the synthesis methods influence the physical make-up and how well MoS 2 works in Supercapacitors, underlining its potential for the future of energy storage.
