2025 MRS Fall Meeting & Exhibit
Symposium CH03-Operando Insights from the Atomic to the Electrode Scale
As the heart of green economy, electrochemistry plays a significant role in chemical production, environmental protection, and energy sustainability. To enable high efficiency in energy storage and conversion, as well as long-term stability in industrial applications, rational design of electrode materials based on holistic understanding of structure-performance relationship is desired. As awareness grows regarding the dynamic nature of electrode materials during reactions, operando characterization is attracting increasing attention with several directions worth attention: (1) correlating multi-scale characterization, from the atomic to the electrode scale, in uncovering the active sites and side reactions for electrochemical processes; (2) multi-dimension imaging unveiling structural/compositional evolution, spatial distribution, and motion of electrode materials during reactions; (3) multi-modal characterization combining structural and compositional change with performance variation; (4) bridging the gap between characterization experiments and industrial applications.
Benefiting from the emergence of advanced characterization techniques, recent years have witnessed revolutionized improvements in spatial, temporal, and energy resolutions. This symposium will highlight the latest development in operando characterization techniques in electrode materials. Dynamics of materials ranging from atomic structures (e.g., EM, STM, AFM) to electrode-scale active sites (e.g., SECM, X-ray), as well as molecular processes on surface (e.g., IR, Raman) will be introduced and discussed. We hope this symposium will bring together a diverse group of researchers from academic, government, and industry roles actively involved in operando characterizations and electrochemistry, stimulating more exploration into novel reaction mechanisms, advanced instrument development, and rational improvement of versatile electrode materials.
