摘　　要：结合模板技术与水热法合成了具有管端开口结构的碳纳米管.采用X射线衍射与电镜对该碳纳米管进行了结构与形貌的表征.电化学测试结果表明,相对于气相沉积法合成的多壁碳纳米管,该方法合成的碳纳米管具有更高的比容量和更好的循环性能.A facile method,combining hydrothermal method with the template technique,was developed to synthesize open-ends carbon nanotubes（CNTs）.X-ray diffraction and electron microscopy analysis techniques were used to characterize the samples.The electrochemical properties of the as-prepared CNTs as anode materials for lithium battery were studied by galvanostatic method.Results showed that the asprepared CNTs displayed higher capacity and superior cycle performance in comparison with the multiwalled carbon nanotubes（MWNTs）.
