摘要

A hybrid of SnO2 nanorods interlaced by unzipped carbon nanotubes (UCNTs) was synthesized by a simple hydrothermal route. The structure and morphology of the nanocomposites were characterized by X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N-2 adsorption/desorption analysis. Both SEM and TEM images show that SnO2 nanorods were interlaced by UCNTs to form a network structure. The galvanostatic charge-discharge experiments showed that the reversible capacity of the hybrid was improved to 856 mA h g(-1) at 0.1 A g(-1) and kept at 541 mA h g(-1) after 50 cycles at various current densities, which was higher than that of bare SnO2 nanorods.
