Symposium CM03—In Situ/Operando Analysis of Electrochemical Materials and Interfaces
Dynamic phenomena across length and time scales often determine the behavior of electrochemical systems for energy conversion and storage. Examples of such phenomena include ion transport, phase transformations in materials, interfacial dynamics, morphological evolution, and electron/ion transfer. These processes are often coupled, and they significantly affect the operation of batteries, electrocatalysts, fuel cells, photoelectrochemical electrodes, and other systems. To design energy storage and conversion systems with significantly improved performance, it is critical to fundamentally understand these dynamic phenomena and how they interact across length and time scales to give rise to the emergent behavior of the system.
This symposium focuses on understanding the dynamic behavior of electrochemical energy systems via the use of in situ and operando experimental techniques. This rapidly advancing field has made great progress in revealing fundamental operational and reaction mechanisms in such systems in recent years. This symposium invites submissions related to a variety of different electrochemical energy storage and conversion devices and systems, including batteries, fuel cells, electrocatalysts, and photoelectrochemical cells. Topics of interest include (but are not limited to) the following: fundamental understanding of interfacial dynamics and (in)stability, phase transformations, ionic transport within materials and devices, chemomechanical effects, mesoscale dynamic behavior, and degradation pathways. A goal of this symposium is to bring together researchers who use different experimental techniques (x-ray, electron, optical, neutron, and scanning probe methods for imaging, spectroscopy, diffraction, and scattering) to discuss results and opportunities related to understanding various aspects of electrochemical behavior. The symposium also encourages submissions in which a multi-modal approach is taken to understand phenomena (i.e., the use of different in situ/operando techniques), as well as studies in which in situ/operando experiments are combined with modeling.
