Abstract

Composite Li ₂ SnO ₃ /C with good cycle performance for lithium-ion batteries was synthesized by a hydrothermal route. The structure, morphology and electrochemical properties of the as-prepared materials were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA) and electrochemical measurements. Results show that the length of the Li ₂ SnO ₃ nanorods are in the range of 40-60 nm while the average diameter is approximately 30 nm. Amorphous carbons are distributed among the Li ₂ SnO ₃ nanoparticles. The first discharge-charge capacities of Li ₂ SnO ₃ /C are 2045.8 mAh g ^-1 and 1756.6 mAh g ^-1 . After the 50th cycles, the capacity retained is 598.3 mAh g ^-1 at a constant current density of 60 mA g ^-1 in the voltage range of 0.05-2.0 V. The composite Li ₂ SnO ₃ /C exhibits a better electrochemical property than Li ₂ SnO ₃ .
