Sb2S3 with Various Nanostructures: Controllable Synthesis, Formation Mechanism, and Electrochemical Performance toward Lithium Storage

The size and shape con trolled synthesis of Sb2S3 nanostructures has been successfully realized by a facile hydrothermal route A range of dimensional nanostructures, such as one-dimensional nanorods two dimensional nanowire bundles three dimensional sheaf-like superstructures, dumb bell-shaped superstructures, and urchin like microspheres, could be obtained through introducing different organic complex reagents or ionic liquids to the reaction system The formation mechanisms of various Sb2S3 nanostructures have been rationally proposed based on the crystal structure and the nature of the complex reagents and the ionic liquid The effects of experimental parameters on the final product are also discussed in detail In addition, electrochemical measurements demonstrate that the as synthesized Sb2S3 nanostructures have higher initial Li intercalation capacity and excellent cyclic performances which indicates that the as-synthesized Sb2S3 nanostructures could have potential applications in commercial batteries
