2D MXene-based supercapacitors: A promising path towards high-performance energy storage

Abstract

MXenes are rapidly emerging as a class of two-dimensional (2D) materials with a wide range of applications in energy storage. MXenes are 2D layered structures, making them the most sought-after material among the 2D family. MXenes are regarded as one of the best electrode materials due to exceptional characteristics, including flexibility, high conductivity, and tunable surface functional groups for advanced energy storage technologies. The demand for high-capacity energy storage devices that are durable, versatile, and cost-effective has grown in tandem with the advancement of technology. MXenes and their composites have significantly improved the performance of energy storage devices. Researchers are continuously exploring new ways to improve MXene's unique properties further. This review article summarizes recent developments in MXene-based electrochemical energy storage devices powered by supercapacitors, which are robust, flexible, and highly efficient. The article also focuses on MXene's structure, synthesis strategies, and how various factors such as electrode architecture design and electrolyte composition affect the charge storage mechanism and electrochemical efficiency of MXene-based supercapacitors.
