Active Sodium Occupancy Ratio‐A Guiding Descriptor for Predicting Na <sub>4</sub> Fe <sub>3</sub> (PO <sub>4</sub> ) <sub>2</sub> P <sub>2</sub> O <sub>7</sub> Sodium Storage Performance
at an ultra-high rate of 50 C and retaining 85.7% of its initial capacity after 20 000 cycles. This work reveals a close correlation between the Na1/Na4 occupancy ratio and the electrochemical performance of NFPP, providing clear design guidelines for developing advanced NFPP cathodes.
