Na4Fe3(PO4)2(P2O7) (NFPP) is a promising cathode material for sodium-ion batteries with cost-effectiveness and structural stability. However, its electrochemical behaviors are seriously hindered by [P2O7] distortion at high voltage. To address this challenge, we introduce criterion optimize the local crystal field environment incorporating Cr3+ into Fe3 sites adjacent to [P2O7]. This substitution elongates Fe1-O bonds, enhances Fe1 activity, suppresses distortion, facilitating fast Na+ diffusion reversibility, as validated X-ray absorption fine structure (XAFS) density functional theory (DFT) calculations. Based on c-axis changes during high-voltage operation, quantitative method assessing proposed confirmed operando diffraction (XRD). The optimized NFPP-0.15Cr exhibits exceptional rate performance (91.74 mAh g-1 50C), long-term cycling stability (88.81% capacity retention after 10,000 cycles wide temperature tolerance (-40 60 °C). study provides strategic approach designing high-performance iron-based mixed phosphate cathodes, advancing their practical application in batteries.

Na4Fe3(PO4)2P2O7 (NFPP) is gradually developing into one of the most commercially prospective cathode materials for sodium-ion batteries. However, inactive phase maricite-NaFePO4 (m-NFP) normally tends to be formed during synthesis process NFPP, as well intrinsic poor electronic conductivity, which impacts realization high Na-storage performance. Herein, first time, we have constructed a heterostructure in Fe-based polyanionic by fine-tuning stoichiometric ratio Na site; m-NFP fully transformed active Na2FeP2O7 or NFPP. In NFPP-NFPO heterogeneous composites, density functional theory calculations reveal that charge redistribution occurs at interface, leading stronger and more uniform interactions can strengthen structural stability enhance transport kinetics. Benefiting from intergrowth structure formation electrochemically phase, discharge specific capacity, ultralong cycle life (71.4% capacity retention after 10,000 cycles 50 C), ultrafast rate capability (60.2 mAh g-1 200 impressive high-temperature tolerance been achieved. This work achieves composites manipulation composition, providing new approach designing high-performance cathodes
