Flowerlike Sb₂S₃/PPy Microspheres Used as Anode Material for High‐Performance Sodium‐Ion Batteries

Abstract

In this work, flowerlike Sb 2 S 3 microspheres have been synthesized with a simple solvothermal reaction and an effective preparation process using polypyrrole (PPy). When tested as an anode for sodium‐ion batteries (SIBs), the flowerlike Sb 2 S 3 /PPy exhibits improved reversibility and cycling performance for SIBs. At a current density of 100 mA g –1 , a capacity of 427 mA h g –1 is maintained after 50 cycles. Even at a high current density of 800 mA g –1 , a reversible capacity of 236 mA h g –1 is obtained.
