Investigation on SnS with various morphologies as anode material for lithium ion batteries

摘要：

SnS with different morphologies and sizes were synthesized by ball milling, microwave-assisted and chemical methods. X-ray diffraction (XRD) measurements proved successful preparation of SnS phases. Observed under transmission electron microscopy (TEM),as-prepared SnS showed various morphologies, including nano particle, flake and nanorod. It was revealed in electrochemical investigation that nano SnS particles prepared by ball milling and chemical method without surfactant had superior electrochemical performances, respectively remaining capacities of 375 mAh/g and 414 mAh/g after 40 cycles. Compact nano structure,morphology and size were responsible for excellent electrochemical performances of nano scale SnS. Although inactive phase Li2S could help maintain stable electrode structure during discharge-charge process, the morphology and size of SnS were the key factors to obtain an outstanding SnS anode.
