Abstract : Phosphate cathodes of sodium‐ion batteries usually exhibit low conductivity, seriously hinders their electrochemical properties. The authors (DOI: 10.1002/inf2.12184 ) of this manuscript regulate the fluorophosphate lattice with increased ionicity via aliovalent substitution, achieving the higher structural stability, improved electron/ion‐transport kinetics, and superior energy‐storage performances in advanced Na3.14 V1.93 Na0.07 (PO4 )2 F3 cathode.
