Whereas electrochemical studies of batteries typically only report the average potential and integrated current of the system as a whole, operando studies provide the opportunity to interrogate functioning electrochemical devices with a powerful combination of spatial sensitivity and temporal sensitivity. A variety of national user facilities have been employed to collect high-quality diffraction data in a high-throughput manner, followed by high-throughput data analysis using a computational infrastructure developed for this purpose. Through these efforts, operando insights have been gained into electrochemical cells configured in an industrially relevant format, providing intriguing insights into phase transformations and local heterogeneity.
