摘要：

Carbon coated vanadium oxide nanostructures were synthesized from the vanadium oxide sol using hydrothermal method with and without H-2 gas atmosphere for the purpose of cathodes in the lithium-ion batteries. The synthesized materials were characterized using x-ray diffraction (XRD) and transmission electron microscopy (TEM). A TEM image shows the thickness of carbon coating is more on vanadium oxide under H-2 gas atmosphere during synthesis. Electrochemical results shows that carbon coated vanadium oxide without H-2 gas atmosphere have higher capacity than the carbon coated vanadium oxide electrode with H-2 gas atmosphere.
