Overcoming Sluggish Kinetics in Na4Fe3(PO4)2P2O7 via Synergistic Zr Doping and Iron Defect Engineering for High-Performance Sodium-Ion Batteries
{{output}}
The Na4Fe3(PO4)2P2O7 (NFPP) cathode material shows promising potential for sodium-ion batteries (SIBs) due to its cost-effectiveness and high theoretical capacity. However, the unavoidable formation of NaFePO4 impurities during synthesis and its poor intrinsic... ...
