Summary:
The versatility of MXenes, pivotal in energy storage (Li-ion batteries, supercapacitors), composites, catalysis, gas sensing, and various applications, necessitates heightened efficiency and reliability. Their unique atomic structure—transition metal carbides, nitrides, or carbonitrides—facilitates diverse functionalities, supported by exceptional traits like high conductivity, mechanical flexibility, and surface reactivity. Yet, complex MXene synthesis and processing demand precision, grappling with structure intricacies. It is within this context that the “Argonne MXene Innovations” initiative emerges as a pioneering, multidisciplinary approach, harnessing cutting-edge science and engineering capabilities. This initiative, integrating supercomputing capabilities for advanced materials design from the Argonne Leadership Computing Facility, leveraging high-resolution X-ray imaging at the Advanced Photon Source, providing nanoscale insights offered by the Center for Nanoscale Materials, and tapping into synthesis expertise at the Materials Engineering Research Facility, is poised to address the complexities inherent in MXene synthesis and scale-up processes. This poster presentation will highlight these capabilities and spotlight specific subprograms—MXBat, MXCat, MXCel, MXFab, MXMech, MXProtect, and MXSense—showcasing the role of MXene in refining energy storage, electrocatalysis, conductivity optimization, synthesis methodologies, mechanical reinforcement, surface protection, and sensing capacities, respectively. These case studies illuminate collaborative achievements, propelling development, enhancing performance, and advancing manufacturing methodologies beyond conventional paradigms.
