Template Synthesis of Tubular Sn-Based Nanostructures for Lithium Ion Storage

Abstract

We report herewith the preparation of SnO₂ nanotubes with very good shape and size control, and with and without a carbon nanotube overlayer, The SnO₂-core/carbon-shell nanotubes are excellent reversible Li ion storage compounds combining the best features of carbon (cyclability) and SnO₂ (capacity) to deliver a high specific capacity (~540-600 mAh/g) simultaneous with good cyclability (0.0375% capacity loss per cycle).
