MXene-Based Nanomaterials for Next- Generation Energy Storage and Flexible Electronics

Abstract

The increasing demand for efficient energy storage technologies and flexible electronic devices has stimulated extensive research into advanced nanomaterials capable of simultaneously delivering high electrochemical performance and mechanical adaptability. MXenes, a rapidly emerging family of two- dimensional transition metal carbides, nitrides, and carbonitrides, have demonstrated exceptional potential in these applications owing to their metallic conductivity, hydrophilic surfaces, tunable chemistry, and layered structures. Among the various MXene compositions reported to date, Ti₃ C₂ Tₓ has received considerable attention due to its ease of synthesis and outstanding electrochemical properties. This study explores the application of MXene-based nanomaterials in next-generation energy storage systems and flexible electronic devices. Particular emphasis is placed on understanding the relationship between MXene structure, surface functionalization, and performance characteristics relevant to supercapacitors, rechargeable batteries, flexible sensors, and wearable technologies. Current advances in synthesis techniques, composite engineering strategies, and device fabrication methodologies are critically discussed. Furthermore, the challenges associated with oxidation stability, sheet restacking, and scalable manufacturing are examined in detail. The findings indicate that MXene nanomaterials possess substantial potential to revolutionize sustainable energy storage technologies and enable the development of mechanically robust electronic systems. Continued efforts directed toward environmentally responsible synthesis routes, interfacial engineering, and multifunctional material design may accelerate the translation of MXene research from laboratory investigations to industrial applications.
