Highcapacity SnS-carbon Nanocomposites as Anodes for Li-ion Batteries with Outstanding Performance
A facile high-energy ball-milling method is developed to synthesize SnS-carbon(SnS-C)nanocomposites,which can be used for industrial mass production.Electrochemical analyses revealed that the SnS-C nanocomposites as anode material in lithium ion batteries(LIBs)showed high discharge capacity and excellent cycling stability.The SnS-C nanocomposite with 50%C showed a discharge capacity as high as 1056 mAh g–1 with the columbic efficiency of 75%in the first cycle and retained the capacity up to 1055 mAh g–1 after 100 cycles at a current density of 100 mA g–1.The excellent electrochemical properties of SnS-C originated from its unique structure,which is composed of SnS nanoparticles embedded carbon network,providing more lithium ion storage sites,higher electronic conductivity,and fast ion diffusion.This work opens a simple way to large-scale production of new SnS-based anode materials with a low cost and good performance for LIBs.
