Abstract

Sodium-Ion Batteries Cathode materials are decisive for the development of sodium-ion batteries (SIBs). In article number 2110108, Xing-Long Wu and co-workers present a high-entropy Na3V2(PO4)2F3-based cathode for advanced SIBs. The high-entropy effect endows this cathode material with a lowered Na+ migration barrier and enhanced electronic conductivity, which jointly promote charge transport and sodium-storage ability in the phosphate cathode, thereby enhancing the average operating voltage and energy density of the SIB.
