ResumoPVP-protected SnO2 nanoparticles and SnO2–graphite nanocomposites were prepared by urea-mediated homogeneous hydrolysis of SnCl4. For unsupported SnO2 TEM examination showed particles in the range of 4–6 nm, and a narrow particle size distribution. The particles also dispersed very well on a graphite surface. The SnO2–graphite nanocomposites prepared as such combine the high specific capacity of Sn-based anodes and the cyclability of graphite, and are promising anode materials for Li ion battery applications.
