Toward Sustainable Sodium-Ion Storage via Local Structural Engineering of Nonstoichiometric Iron-Based Mixed Phosphate–Pyrophosphate Cathodes

The nonstoichiometric iron-based mixed phosphate (Na5.12Fe4.44(PO4)2(P2O7)2, N5.12FPP) has emerged as a promising cathode material for sodium-ion batteries (SIBs), benefiting from its low cost, intrinsic safety, and robust structural framework. However, its practical application remains limited by intrinsically low e...
