Anion Chemistry: Structure, Electrochemistry and Stability of NASICON Cathodes

Caption

  • Na3V2(PO4)2F3 and Na3V2O2(PO4)2F are systematically compared to elucidate the influence of subtle anion chemistry differences on crystal structure and Na+ ions diffusion pathways.
  • Synthesis and modification strategies are critically evaluated to clarify the relationships among structure, properties, and performance in fluorophosphate NASICON cathodes.
  • Voltage-driven interfacial degradation mechanisms are analyzed, providing transferable insights for designing durable high-voltage sodium-ion battery cathodes.
