Synthesis of tin-carbon composite by RF (resorcinol-formaldehyde) sol method and their applications as lithium battery anodes.
Sn/C composites were prepared by hydrothermal treatment from a mixture of tin tetrachloride pentahydrate (SnCl4 x 5H2O) and resorcinol-formaldehyde gel (RF gel). Particle size was controlled by varying initial pH of the mixture, and particle size distribution was very narrow. Scanning electron microscopy (SEM) was utilized to examine surface morphology and particle size. Composition was determined by energy dispersive spectrometer (EDS), and crystallinity of synthesized samples was investigated by XRD and Raman spectroscopy. The electrochemical properties of synthesized samples as anodes for Li-ion batteries were investigated in coin cells. The electrochemical performance as an anode was found to be strongly dependent on particle size.
