Synthesis and electrochemical performance of hierarchical Sb 2 S 3 nanorod-bundles for lithium-ion batteries

Uniform hierarchical Sb2S3 nanorod-bundles were synthesised successfully by L-cysteine hydrochloride-assisted solvothermal treatment, and were then characterised by X-ray diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy, respectively. The electrochemical performance of the synthesised Sb2S3 nanorod-bundles was investigated by cyclic voltammetry and galvanostatic charge−discharge technique, respectively. This material was found to exhibit a high initial charge specific capacity of 803 mA h g at a rate of 100 mA g, a good cyclability of 614 mA h g at a rate of 100 mA g after 30 cycles, and a good rate capability of 400 mA h g at a rate of 500 mA g when evaluated as an electrode candidate material for lithium-ion batteries.
