Abstract Structural design combined with crystal engineering is an external and internal modifying strategy for metal oxides sulfides as anode materials lithium/sodium‐ion batteries (LIBs/SIBs). In this paper, the low‐cost iron‐based oxide of Fe 2 O 3 shaped into dendritic nanostructure locally in situ phase converted to FeS form porous /FeS polycrystalline texture. The maintains original porous, cross‐linked low‐dimension structural advantages precursor electron transport ions exchange alleviating volume expansion. Then, abundant heterogeneous dramatically enhances diffusion stability at boundary. prepared achieves superior rate capability ultra‐long cycling high capacity both LIBs SIBs. Specially, it shows 1017 1016 mAh g −1 10 A SIBs, separately. After 3000 cycles, electrodes maintain 266 279 addition, LiFePO 4 //Fe (Na V (PO ) )//Fe full cells are successfully packaged also show satisfactory electrochemical performances.
