Progress in development of MXene-based nanocomposites for supercapacitor application-A review

Abstract

During the time of the industrial revolution, there was a growing need for energy storage composites that were dependable, high-performing and possessed qualities like flexibility, affordability, and durability. The advancements in electronics and other related technologies drove this demand. The mechanical, physical, and optical characteristics of MXene (a class of two-dimensional inorganic compounds) materials have attracted significant attention in the present century due to their suitability for manufacturing high-performance energy storage devices. MXenes significantly improve the energy storage capabilities of supercapacitors by offering shorter ion diffusion paths, excellent conductivity, and a vast surface area. The hydrophilicity of MXenes, along with their surface redox processes and metallic conductivity, plays a crucial role in enabling high-rate and high-performance pseudocapacitive energy storage materials. Throughout this overview, we have explored the process of synthesizing MXene, its unique properties, and the mechanisms of charge storage. We have thoroughly explored the latest progress and discoveries in nanocomposites based on MXene. After evaluating the potential of MXene composites for creating environmentally friendly energy storage materials with impressive performance, we discussed the future challenges and possibilities of this field.
