Local structural modulation via sulfate substitution for high-performance NFPP-based sodium-ion battery cathode

Sodium-ion batteries (SIBs) are compelling low-cost candidates for large-scale energy storage. Nevertheless, NASICON-type Na 4 Fe 3 (PO 4 ) 2 P 2 O 7 (NFPP) polyanionic cathodes suffer from intrinsically inferior electronic conductivity and sluggish Na + diffusion, severely restr...
