Electrochemistry plays a central role in the storage or conversion of renewable energies. As such, it is at work in a variety of emerging sustainable technologies and devices, significantly impacting society. Optimizing the performance of these devices requires a deep understanding of electrochemical reaction mechanisms at the ultimate scales, as they are closely related to the microstructure of materials. Therefore, it is crucial to provide multiple and complementary structural characterizations, with high spatio-temporal resolution, of these electroactive materials, and ideally in operation (operando).

The recent development of operando imaging techniques reflects this increased interest. These innovative techniques for observing materials, in situ and during their electrochemical operation, improve our ability to understand their dynamic structural modifications, and to establish correlations between performance and microscopic structure. Among these, operando optical microscopy stands out for several major advantages: extreme sensitivity, high spatial and temporal resolution, high throughput analysis, low invasiveness, and easy implementation.

This conference aims to present major advances in the use of operando optical imaging techniques, in order to develop an advanced understanding of microscopic electrochemical reactions related to the storage and conversion of energy. It will highlight the principles and latest innovations, both in terms of instruments and analytical approaches, encompassing experimental, theoretical studies, and data analysis.

These advances transform optical microscopy into an essential tool for the discovery and development of new, high-performance materials and devices.

Frederic Kanoufi is a CNRS senior researcher, team leader in ITODYS laboratory at Universite Paris Cite, in Paris, France. After a PhD on electrochemical methods for polymer functionnalization he joined Pr Allen J Bard group as a postdoctoral fellow at the University of Texas at Austin (1999) where he studied Electrochemiluminescence (ECL) and scanning electrochemical microscopy (SECM). He then obtained a CNRS  researcher position in Paris. He initiated scientific activity related to the electrochemical imaging or functionnalization of interfaces, first using SECM then since 10 years by coupling electrochemistry with super-resolution optical microscopies methodologies. He was awarded the CNRS Bronze medal (early-career award) in 2006 for the activity on SECM, while obtained the French Physics and Chemistry Societies instrumentation prize for the opto-electrochemical coupling in 2015.He has published +190 articles and several review or book chapters related to electrochemical imaging methodologies. His activity initially related to surface functionnalization and molecular electrochemistry, are more recently extended to electrochemical energy storage and conversion.
