Development of MXene-based Nanocomposites for Next-Generation Supercapacitors

Abstract

The increasing demand for high-performance energy storage devices has driven extensive research into next-generation supercapacitor materials. Among them, MXenes—two-dimensional transition metal carbides and nitrides—have emerged as promising candidates due to their exceptional electrical conductivity, tunable surface chemistry, and hydrophilicity. This study focuses on the development of MXene-based nanocomposites by integrating Ti₃C₂Tx MXenes with conductive carbon nanomaterials such as graphene oxide (GO) and carbon nanotubes (CNTs). The resulting hybrid structures exhibit synergistic properties, including enhanced electrochemical stability, increased specific surface area, and superior ion transport. Advanced synthesis techniques such as vacuum-assisted filtration and freeze-drying were employed to fabricate binder-free electrode films. Electrochemical performance was evaluated through cyclic voltammetry, galvanostatic charge–discharge, and electrochemical impedance spectroscopy. The optimized nanocomposites achieved a specific capacitance exceeding 1000 F/g and maintained over 95% capacitance retention after 10,000 cycles. These findings underscore the potential of MXene-based nanocomposites in advancing scalable, high-efficiency supercapacitor technologies for sustainable energy systems.
