The ambitious goal of reaching a detailed understanding of electrochemical reactions mechanisms within and on the surface of the constituent materials of Li-ion batteries has generated the development of an arsenal of physicochemical characterization techniques, especially in situ or operando, which are ...
Understanding, controlling and tuning the interfaces in energy conversion and storage materials requires in situ/operando characterization tools, of which synchrotron X-ray spectroscopies, which have several unique features, are very suitable ones. X-ray absorption spectroscopy can be used to elucidate ...
between electrocatalyst and varied environment, dynamic configurations at different landscape from interface, surface to bulk phase are considerably complicated, and thus it is pressing to combine several complementary in situ/operando techniques for deciphering a whole picture of dynamic solid–liquid ...
Operando characterization, a growing area of research, elucidates the understanding of catalyst properties “in action” (under operating conditions). The accuracy and reliability of operando studies are dictated by appropriate selection, validation, and use of reference electrodes. The impact on the ...
Overall, this somewhat limits the possibility of operando investigations beyond the first cycle and, in particular, hinders further understanding of the reaction and degradation mechanisms under realistic conditions. To gain more insight into the behavior of the HEO anode during electrochemical cycling, ...
Advanced Characterization Techniques: novel techniques such as in-situ electron microscopy, operando spectroscopy, or advanced neutron scattering that reveal material behaviors under real-world conditions Sustainable materials science: materials for a circular economy, substitution of critical elements, engineered...
