Carbon-coated Si has been prepared by thermal vapor decomposition technique. The electrochemical behaviors of carbon-coated Si together with Si have been investigated as anode materials for lithium-ion batteries. The good cycleability of carbon-coated Si under lithiation capacity of 1200 mA h/g has been correlated with ex situ XRD patterns as well as SEM graphs.
