Abstract

Abstract: A combination of high-energy ball milling and constant pressure chemical vapor deposition was used to prepare carbon-coated SiO/ZrO2 composites. It was found that the as-prepared composites were composed of amorphous carbon, amorphous SiO, and paracryslalline ZrO2 . The electrochemical analysis results revealed excellent electrochemical performances for the composites, including a high initial discharge capacity (1737 mA h g −1 ), a remarkable cyclic stability (reversible capacity of 721 mA h g −1 at 800 mA g −1, after 100 cycles), and a good rate capability (870 mA h g −1 at 800 mA g −1 ). These features demonstrate that these composites are promising alternative candidates for high-efficiency electrode materials of Li-ion batteries.
