Mapping Heterogeneity of Pristine and Aged Li‐ and Na‐Mnhcf Cathode by Synchrotron‐Based Energy‐Dependent Full Field Transmission X‐ray Microscopy (Small Methods 11/2023)

Inside Back Cover In article number 2300718, Tonti, Giorgetti, and co-workers demonstrated the formation of charge state inhomogeneities inside the Manganese hexacyanoferrate cathode material via synchrotron-based transmission soft X-ray microscopy. Special image treatment procedure was adopted to highlight the heterogeneities on Fe and Mn oxidation state. The advantage of using Na-ion system over Li-one were detected.
