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 insitu 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.
