Ti-Doped Na4Fe3(PO4)2P2O7/C Cathode Synthesized via a Low-Cost Solid-State Method for High-Performance Sodium-Ion Batteries
Na4Fe3(PO4)2P2O7 (NFPP) is regarded as a highly promising cathode material for sodium-ion batteries (SIBs) in energy storage systems. In particular, the low cost and environmental friendliness of NFPP render it especially suitable for large-scale commercialization. Nevertheless, the inherently low ionic/electronic co...
