Effect of Mn-to-Fe Substitution on the Dehydration Mechanism and Electrochemical Properties of Prussian White Materials for Na-Ion Batteries

Adélaïde Clavelin, Marcus Fehse, Dimitrios Chatzogiannakis, Carlos Escudero et autres

Abstract In this study, we investigated the impact of partial Mn-to-Fe substitution on the dehydration mechanism and electrochemical performance of Mn-hexacyanoferrates (Prussian White) as positive electrode active materials for sodium-ion batteries. In situ synchrotron temperature experiments revealed similar phase transitions during drying …
