Abstract
MXenes, an exceptional class of materials that are present in all dimension forms, have garnered significant interest owing to their enormous potential in electrochemical energy storage. The article encompasses different synthesis techniques and their effect on the structure, electrical properties, and surface properties of MXenes. We highlighted the recent development in composition optimization, surface engineering, and structure design has achieved remarkable device performance with reported specific capacitance values ranging from 100 to 1000 mF/cm2. The application of machine learning to surface feature optimization and MXene structure prediction is also mentioned. Furthermore, the MXene mechanistic insights by operando and in situ characterization techniques such as in situ Raman spectroscopy, synchrotron XRD, and XANS is discussed. These methods explored the structure evolution, oxidation state, and charge transport upon operation. In short, we envision the integration of MXene with advanced techniques of electrode preparation like inkjet printing, screen printing, and additive manufacturing. These methods provide high-resolution, tuneable, and scalable patterning of electrodes and hence establish possibilities for applications in microsupercapacitors. The purpose of this review is to give a holistic picture of the design approaches of MXene properties by synthesis and processing techniques, and to describe the scaling from laboratory-scale concepts to energy storage applications.
