Recent Developments in Electrodeposition of Transition Metal Chalcogenides-based Electrode Materials for Advance Supercapacitor Applications: A Review

Abstract

High-performance supercapacitive electrode materials have received significant attention from researchers worldwide, thus aiming for comparable performance similar to the extensively used rechargeable batteries. For emerging energy storage technologies like flexible supercapacitors, transition metal chalcogenides (TMCs) have been in the spotlight due to their promising electrochemical features compared to other electrode materials. Among the synthesis techniques, electrodeposition-mediated preparation of thin films of TMCs offered an affordable binder-free approach for electrode fabrication that effectively improved the supercapacitor performance. Hence, this review mainly focussed on the electrodeposition-based syntheses of single/ multinary chalcogenides and their composites for supercapacitors applications. Further, the effects of different deposition parameters were discussed for boosting the supercapacitor performance. Finally, this review outlined the existing challenges and future perspectives in this research domain, which will assist the upcoming exploration in the energy storage field. This review focuses on the electrodeposition-mediated synthesis of thin films of single/multinary transition metal chalcogenides for advanced supercapacitor applications. Different composites of chalcogenides and the effect of varying different deposition parameters for tuning the supercapacitor performance have been discussed. Lastly, existing challenges and perspectives in this area have been highlighted.image
