Solvothermal Synthesis of the SnO_2 Nanomaterial for Highly Reversible Lithium Storage

摘要

The SnO_2 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 SnO_2 nanorods with diameter of about 10 nm and length of 30 nm. When used as anode materials for lithium ion batteries, the prepared SnO_2 nanomaterial exhibited a relatively high reversible capacity of 950.9 mAh·g~(-1) and excellent cycling stability. The enhanced electrochemical performance of the SnO_2 nanomaterial could be attributed to the unique nanostructure, which could accommodate the large volume change during cycling and provide an excellent electronic conduction pathway.
