Resolving the Role of Configurational Entropy in Improving Cycling Performance of Multicomponent Hexacyanoferrate Cathodes for Sodium‐Ion Batteries (Adv. Funct. Mater. 34/2022)

Configurational Entropy In article number 2202372, Yuan Ma, Ben Breitung, Torsten Brezesinski, and co-workers report the preparation and characterization of Mn-based multicomponent hexacyanoferrate cathodes for application in Na-ion batteries. Systematic comparison of the structural, chemical, and electrochemical properties of high-, medium- and low-entropy materials uncover the origin of improved cycling performance and stability, namely entropy-mediated suppression of adverse side reactions and phase transitions.
