摘要: Hierarchical Sb2S3 hollow microspheres assembled by nanowires have been successfully synthesized a simple and practical hydrothermal reaction. The possible formation process of this architecture was investigated X-ray diffraction, focused-ion beam-scanning electron microscopy dual-beam system, transmission microscopy. When used as the anode material for lithium-ion batteries, manifest excellent rate property enhanced lithium-storage capability can deliver discharge capacity 674 mAh g−1 at current density 200 mA g−1 after 50 cycles. Even high 5000 mA g−1, 541 mAh g−1 is achieved. also display prominent sodium-storage maintain reversible 384 mAh g−1 remarkable lithium/sodium-storage may be attributed to synergetic effect its nanometer size three-dimensional hierarchical architecture, outstanding stability sufficient interior void space, which buffer volume expansion.
