Flower-like Sb2S3/PPy microspheres used as anode material for high-performance sodium-ion batteries

Guangda Li, Yanxin Shen, Lingxue Zhao, Tian Zheng
In this work, flower-like Sb2S3 have been successfully synthesized with a simple solvothermal reaction and effective preparation process using polypyrrole (PPy). When tested as an anode for sodium-ion batteries, the flower-like Sb2S3/PPy exhibited improved reversibility and cycling performance as anode materials 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 current density of 800 mA g-1, a reversible capacity of 236 mA h g-1 is obtained.
