Antimony‐based electrode materials with high specific capacity have aroused considerable interest as anode materials for sodium‐ion batteries (SIBs). Herein, we develop a template‐engaged ion‐exchange method to synthesize Sb2Se3 microclips, and the as‐obtained Sb2Se3 microclips are further in situ coated with polypyrrole (PPy). Benefiting from the structural and compositional merits, these PPy‐coated Sb2Se3 microclips exhibit enhanced sodium‐storage properties in terms of high reversible capacity, superior rate capability, and stable cycling performance.
