Elucidating Gas Evolution of Prussian White Cathodes for Sodium‐ion Battery Application: The Effect of Electrolyte and Moisture

AbstractInvited for this month's cover picture is the group of Torsten Brezesinski at KIT. The cover picture shows gases evolving from a Prussian white cathode used in Na‐ion batteries in the presence of either NaPF6‐ or NaClO4‐containing electrolyte. H2 and CO2 are detected, as well as (CN)2, for which a formation mechanism is proposed. Read the full text of the Research Article at 10.1002/batt.202300595.
