Metal phosphides (MPs) have emerged as a new class of high‐capacity and low‐cost anodes for sodium‐ion batteries (SIBs). In order to buffer the volume change during the sodiation process and improve the conductivity, we synthesized a porous composite made of FeP nanoparticles uniformly anchored on 3D reduced graphene oxide structure (FeP@rGO) by a low‐temperature chemical solution deposition method with subsequent phosphorization and thermal reduction processes. Electrochemical characterization indicated that the FeP@rGO composite nanostructured anode delivers an attractive reversible capacity up to 366.6 mAh g −1 with superior cycling stability (388.8 mAh g −1 after 250 cycles) and high Coulombic efficiency (>99%), which is among the previously reported high performance transition MPs‐based SIBs anode materials.
