【 摘 要 】

Two-dimensional Sn-based metal compounds (e.g. SnS, SnS2 and SnO2) are exceptionally attractive due to their excellent ion intercalation response and are suitable for use in energy storage devices (e.g. lithium -ion batteries and supercapacitors). However, the application of these dichalcogenides in Li -ion batteries is hindered by limitations in large-scale solution synthesis of SnS nanobelts. In this study, we developed a universal hydrothermal approach for the synthesis of SnS nanobelts and proposed an underlying mechanism for the formation reaction. When used as anode materials for lithium -ion batteries, SnS nanobelts maintain a discharge capacity of 889.9 mAhg(-1) after 50 cycles at a current density of 0.1 A/g. The nanobelts also exhibit high electrochemical performance, high rate capacity, and high reversible capacity. These results demonstrate that SnS nanobelts are potential anode materials for highperformance energy storage applications. (C) 2016 Elsevier B.V. All rights reserved.
