This symposium covers recent progress in the multiscale advanced characterization of energy materials to understand the foundations of the physico-chemical phenomena that determine performances as a way to design more efficient and durable materials. The first part focuses on investigations of the physical/chemical processes and materials behaviour in reversible batteries, electrolysis, fuel cells, etc. Techniques of interest for multiscale in situ studies are TEM, XAFS, XRD, XPS, X-ray tomography and SIMS, to name a few. The second part focuses on electrochemical reactions under extreme environments such as high/low temperatures and pressure, large temperature fluctuations, irradiation, etc. The contributions address basic scientific issues, discover of new phenomena, limiting factors in the practical application of emerging energy materials. Examples of the translation of fundamental knowledge from the advanced characterization techniques on materials/device development are welcomed, together with complementary computational studies. This symposium aims to cover the state-of-the-art of our understanding of energy materials chemistry, identify synergy between different techniques and applications and is an opportunity to discuss generalised concepts from a fundamental perspective.
