Layered Transition Metal Sulfides for Supercapacitor Applications

ChemElectroChem, Journal Year: 2024, Volume and Issue: 11(11)

Published: Feb. 6, 2024

Abstract Supercapacitor (SC) devices holds an important position between traditional capacitors and ion batteries in terms of energy density power values. In particular, SC′s greater values than Li‐ion make them useful for some specific applications, such as storing hybrid cars while the car slows down. Increasing is one key challenges SC community. Transition metal dichalcogenides (TMDCs), are new developing material systems to have this potential, compared their counterparts’ transition oxides conductive polymers. This review about giving insight into electrochemical performances two‐dimensional (2D) layered sulfides (TMS) MoS 2 , WS TaS NbS VS TiS ZrS materials. On other hand, methods mostly used synthesizing these materials presented.
