Rethinking Performance Degradation in MXene Lithium-Ion Batteries through Coupled Electrochemical Evolution

High Resolution Image Download MS PowerPoint Slide Achieving reliable control over performance stability and interfacial degradation in lithium-ion batteries requires understanding how materials evolve during operation. Increasingly, these limitations emerge from coupled processes at electrode−electrolyte interfaces, where interphase formation, ion transport, and structural changes occur simultaneously during cycling. We examine how these processes shape battery behavior under practical conditions and discuss MXene-based electrodes as model systems for interrogating these effects, with implications for their interfacial and structural complexity. Finally, key directions are outlined toward improved understanding and control of interface-driven processes in MXene-based lithium-ion systems.
