Formation of Polypyrrole‐Coated Sb₂Se₃ Microclips with Enhanced Sodium‐Storage Properties

Abstract

Abstract 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 Sb 2 Se 3 microclips, and the as‐obtained Sb 2 Se 3 microclips are further in situ coated with polypyrrole (PPy). Benefiting from the structural and compositional merits, these PPy‐coated Sb 2 Se 3 microclips exhibit enhanced sodium‐storage properties in terms of high reversible capacity, superior rate capability, and stable cycling performance.
