| Abstract: | The carbon nano-tubes were pured by oxidation method,which was byproduct in coal-coking industry.X-ray diffraction and transmission electron microscope were used to determine the sizes and morphology of carbon nano-tubes.The results showed that the carbon nano-tubes pured were of the structure of graphite and high order degree of graphitization,whose d_(002) value was 0.3496nm.The electrochemical properties of carbon nano-tubes were researched and it exhibited a high electrochemical capacity,being 584.3mAh/g at first cycle.When adding graphite powder and forming 20% carbon nano-tubes +80% graphite powder,it was of 490.1mAh/g at first discharge specific capacity. |
