Abstract
Electrochemistry plays a central role in the storage and conversion of renewable energies. It is also at work in a variety of emerging sustainable technologies and devices that have a significant impact on society. Optimizing the performance of these devices requires an in-depth understanding of electrochemical reaction mechanisms at the ultimate scales, as they are closely linked to the microstructure of materials. It is therefore essential to provide multiple and complementary structural characterizations of these electroactive materials, at high spatio-temporal resolution, and ideally in operation (operando).
The recent development of operando imaging techniques bears witness to this growing interest. These innovative techniques for observing materials, in situ and during electrochemical operation, enhance our ability to understand their dynamic structural changes, and to establish correlations between performance and microscopic structure. Among them, operando optical microscopy stands out for several major advantages : extreme sensitivity, high spatial and temporal resolution, high analysis throughput, low invasiveness and ease of implementation.
This conference aims to present major advances in the use of optical operando imaging techniques to develop an advanced understanding of microscopic electrochemical reactions related to energy storage and conversion. It will highlight the latest innovations in both instrumentation and analytical approaches, encompassing experimental, theoretical and data analysis studies.
These advances are transforming optical microscopy into an essential tool for the discovery and development of new high-performance materials and devices.
