SnS nanoflowers as an efficient anode for next generation lithium-ion batteries

Tin (II) Sulfide (SnS) nanoflowers are synthesized by hydrothermal method. The electrochemical performance of SnS nanoflower versus Li/Li+ + is studied. X-ray diffraction and X-ray photoelectron spectroscopy results confirms the formation of SnS. Scanning electron microscope images validate the existence of nanoflowers. SnS vs. Li/Li+ + half-cell delivers the first charge/discharge capacity of 847.2/853 mAh g(-1) at 0.1 C-rate, with a columbic efficiency of 99 %. Differential capacity versus voltage plot reveals intercalation and deintercalation of lithium ions during cycling and also delves the conversion and alloying reaction of SnS anodes. The better electrochemical result could be ascribed to the flower like morphology, which improves lithium diffusion and reaction kinetics.
