ABSTRACT Na 4 Fe 3 (PO 4 ) 2 P 2 O 7 (NFPP) cathode material exhibits a robust structural stability, conferring long cycle life for sodium‐ion batteries. Nevertheless, the intrinsically low electronic and ionic conductivities of NFPP impede its widespread practical applications. Herein, a high‐throughput density functional theory screening paradigm coupled with experimental validation, was employed to systematically identify and optimize dopants for NFPP, enhancing its electrochemical performanc
