ABSTRACT
Supercapacitor technology, irrespective of high power densities, eco-friendliness, high life cycle efficacies, and mechanical flexibility has not accomplished commercialization to date in full success because of poor energy density, limited operating voltage, and self-discharge issues. Accordingly, global research is focussing on developing smart nanomaterials through well-controlled synthesis that can fruitfully overcome the existing technical restrictions. Molybdenum disulphide (MoS2), is one of the distinctive 2D layered transition metal dichalcogenides that have fascinated the worldwide scientific community in the challenging areas of electrochemical energy generation, storage and conversion systems, owing to its unique layered morphology favouring wide specific surface area, polymorphism varying with oxidation states, characteristic surface topography, distinguished atomic structure facilitating advanced electronic and electrochemical features and so on. Nonetheless, low electronic conductivity and structural instability are the main obstacles to the development of MoS2-based nanomaterials in this technological sector. In this book chapter, we summarize the basic knowledge of its structure and electronic features, preparation and necessary structural modifications required for essential tuning of the intrinsic electronic arrangements for their effective deployment in the field of energy conversion and storage. Finally, the corresponding challenges faced while handling these layered nanomaterials and the prospects have also been highlighted.
