Workshop Summary: To achieve net-zero emissions, the rapid transformation will be required across all global systems. Among different approaches toward this goal, electrochemical energy conversion, (e.g. fuel cells) and energy storage (e.g. rechargeable batteries) materials will play a vital role in this transition. To develop more efficient energy storage devices, the comprehensive characterization techniques are needed to reveal the fundamental questions, e.g., dynamics of processing, phase transformations, intercalation chemistry, surface chemistry, etc.
Synchrotron X-rays allow for nondestructive characterizations with various depth sensitivities through spectroscopy, scattering, and imaging capabilities in multiple scale length. The fast collection time and refined temporal resolution mask the in situ study of the reactions under different environments possible. This workshop will bring together people who are using synchrotron methods on batteries and fuel cells, with potential new users in the electrochemical energy materials community. Our goal is to create a platform for both experts and new users to share new techniques, ignite great ideas and discuss the common challenges. This will educate and inform new users in this growing area of interest, to help them develop experiences in collection, processing, and advanced analysis of synchrotron data on electrochemical energy materials.
