摘要：

Large scale SnO2 core-shell microspheres were synthesized by using a facile template free hydrothermal route. The as-prepared core-shell microspheres were characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM). The electrochemical measurements showed that SnO2 core-shell nanostructures possess excellent electrochemical performance with high capacity of 558.2 nnA h g(-1) after 20 cycles. The enhanced electrochemical performance of SnO2 microspheres is proposed to derive from the advantageous nanostructures that allow better structural flexibility, shorter diffusion length, and easier interaction with lithium.
