Sn/C composites have attracted great attention as anode materials for Li-ion batteries. In this work, Sn/C composites were prepared by hydrothermal treatment of a mixture of tin tetrachloride pentahydrate (SnCl4·5H2O) and resorcinol-formaldehyde gel. The particle size was controlled by varying initial pH of the mixture. To load tin particles on the surface of Sn/C composite, proper amount of SnCl4 was added into an aqueous suspension of Sn/C composite with vigorous stirring, and then mixed suspension was heated in a teflon-sealed autoclave. Synthesized samples were characterized by SEM-EDS, XRD, and Raman spectroscopy. The electrochemical properties as anodes of Li-ion batteries were investigated in coin cells. |
