Facile synthesis of symmetric bundle-like Sb2S3 micron-structures and their application in lithium-ion battery anodes

Abstract

A novel two-step oxidation–sulfuration route is developed to fabricate the symmetric bundle-like Sb₂S₃ micron-structure, in which hundreds of one-dimensional Sb₂S₃ nanowires are tied. As an anode material for lithium-ion batteries, the bundle-like Sb₂S₃ delivers a discharge capacity of 548 mA h g⁻¹ after 100 cycles, much higher than the rod-like one.
