Solvothermal Synthesis of the SnO2 Nanomaterial for Highly Reversible Lithium Storage

The SnO2 nanomaterial for highly reversible lithium storage was successfully synthesized via a simple solvothermal route at a low temperature. According to the XRD and TEM analysis, the nanostructure and the morphology of the obtained samples were constructed by ultrathin SnO2 nanorods with diameter of about 10 nm and length of 30 nm. When used as anode materials for lithium ion batteries, the prepared SnO2 nanomaterial exhibited a relatively high reversible capacity of 950.9 mAh.g(-1) and excellent cycling stability. The enhanced electrochemical performance of the SnO2 nanomaterial could be attributed to the unique nanostructure, which could accommodate the large volume change during cycling and provide an excellent electronic conduction pathway.
