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.

Abstract:

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 as-prepared CNTs displayed higher capacity and superior cycle performance in comparison with the multiwalled carbon nanotubes(MWNTs).

Key words: Carbon nanotube; Lithium-ion battery; Anode material
