Abstract
Novel Zn2SnO4@C core–shell nanorods have been prepared by a simple hydrothermal and subsequent carbonization approach. A series of morphology and structural characteristics are conducted on the obtained material, including X-ray diffraction, transmission electron microscopy combined with energy-dispersive X-ray spectrometer, high-resolution transmission electron microscopy, Raman spectroscopy, and thermal gravimetric analysis, followed by electrochemical study. When evaluating as anode materials for lithium-ion batteries, the as-synthesized Zn2SnO4@C core–shell nanorods exhibit improved electrochemical properties with higher Li storage capacity and longer cycle life compared to the pristine Zn2SnO4 nanorods. The novel core–shell nano structure with excellent buffering effect and better Li storage performance provide a promising use of anode material for Li ion battery.
