摘要

Energy storage technologies including batteries, supercapacitors and fuel cells are essential to cater the energy storage needs of modern electronics, electric vehicles, and renewable energy systems. Among emerging materials, MXene offer great potential in reforming the electrode design due to high capacitance, energy and power densities and conductivity. The electrochemical performance of MXene electrodes has been increasingly affected by their surface chemistry and morphology. Various types of MXene and their derivatives such as Ti3C2Tx and V2CTx have been examined with different battery and supercapacitor materials like lithium, sodium and zinc, demonstrating promising electrochemical properties and performance enhancements. Moreover, functionalized MXenes have shown enhanced electrochemical stability and cyclic stability in metal-ion batteries, and pseudocapacitive behavior in supercapacitors. The compatibility of distinctive materials with MXene to form composite electrode and their synthesis method also have high influence on their performance in energy storage system. Therefore, several approaches have been developed in the recent times, such as hybridization, elemental doping, and controlled interlayer spacing that can be explored and advanced further. These strategies provide a substantial solution to restacking of MXene nanosheets, modest ion transportation and energy storing capacity. This review explores the advancements, emphasizing the evolving role of MXene in next-generation storage technologies.
