Abstract

Inside Front Cover In article number 2500827, Jo and co-workers highlight the critical role of electrolyte composition in modulating the reactivity of crystal water at the Prussian blue (PB) cathode–electrolyte interface in sodium-ion batteries (SIBs). NaTFSI mitigates interfacial degradation by disrupting hydrogen-bond networks and suppressing water-mediated side reactions, whereas NaClO4 intensifies water coordination, inducing cathode-electrolyte interphase instability. These findings provide valuable guidance for optimizing electrolytes in PB-based SIBs.
