Abstract

Nanostructured SnO₂ and SnO₂-graphite composites were prepared by microemulsion synthesis using Tergitol 15-S-5 as the surfactant. The size of the SnO₂ nanoparticles was typically between 15 and 20 nm. The graphite-SnO₂ composite containing 9.8 wt% SnO₂ showed a high reversible Li⁺ storage capacity of 384 mAh/g which decreased by only 4% in 30 cycles. The substantial cyclability improvement relative to unsupported SnO₂ is believed to be due to the uniform dispersion of the SnO₂ nanoparticles on the graphite surface, which reduces particle aggregation during Li⁺ insertion and extraction reactions.
