By adopting the hydrothermal method, different morphologies of antimony sulfide (Sb2S3) can be prepared with antimony potassium tartrate and sodium thiosulfate, with Thiourea as the sulfur source. Such testing approaches as XRD, SEM, EDS, cyclic voltammetry (CV) and constant current charge and discharge have been adopted for an exploration of the effects of different sulfur sources on morphologies and electrochemical properties of Sb2S3. The results show that different sulfur sources have a relatively great influence on the morphology and structure of Sb2S3, which mainly forms thick rod-like structure using sodium thiosulfate as sulfur source; while the fine rod-like structure can be obtained with thiourea as sulfur source. The electrochemical performance of the Sb2S3 sample synthesized by sodium thiosulfate is much better under the current density of 0.1C, with its discharge specific capacity up to 618.6 mA h/g.
