Abstract Sodium‐ion batteries (SIBs) offer promising advantages over lithium‐ion (LIBs) due to sodium's abundance and lower cost. However, challenges like thick solid electrolyte interphase (SEI) layers the larger radius of sodium (1.02 Å vs. 0.76 for lithium) make graphite, most common LIB anode, unsuitable SIBs. To realize maximum potential carbon anode SIBs, one main strategies is fabricate materials with tailored microstructures enhance redox reactivity by incorporating catalytic metals. In this work, Fe‐Fe3C nanoparticles embedded in worm‐like graphitic (Fe‐Fe3C@GC) were synthesized a simple chemical vapor deposition. This hybrid structure promotes activity achieve additional capacities through reversible SEI layer formation, detail, interconversion ester ether derivatives as well conductivity enhancement. Furthermore, situ formed Fe2O3 from Fe(0) contributed extra capacity. The Fe‐Fe3C@GC showed large discharge capacity 376.2 mAh g −1 fading rate 0.013% per cycle after 1000 cycles at current density 50 mA . A full cell coupled an FeOF cathode delivered high energy 602.8 Wh kg
