Colloidal Antimony Sulfide Nanoparticles as a High-Performance Anode Material for Li-ion and Na-ion Batteries.

ABSTRACT: To maximize the anodic charge storage capacity of Li-ion and Na-ion batteries (LIBs and SIBs, respectively), the conversion-alloying-type Sb₂S₃ anode has attracted considerable interest because of its merits of a high theoretical capacity of 946 mAh g^-1 and a suitable anodic lithiation/delithiation voltage window of 0.1-2 V vs. Li⁺/Li. Recent advances in nanostructuring of the Sb₂S₃ anode provide an effective way of mitigating the challenges of structure conversion and volume expansion upon lithiation/sodiation that severely hinder the Sb₂S₃ cycling stability. In this context, we report uniformly sized colloidal Sb₂S₃ nanoparticles (NPs) as a model Sb₂S₃ anode
