摘　　要：由于碳纳米管的特殊结构导致独特的物理化学性质 ,使得它在各个领域的应用引起多方面重视。根据国内外碳纳米管开发利用现状 ,总结了近年来各种不同规格碳纳米管在电化学储氢、电化学储锂、电化学电容器等电化学储能方面的研究进展 ;指出了各方面研究发现的问题 ,如电化学储锂的电压滞后 ,不可逆容量较大 ,电化学储氢时氢在碳纳米管中的存在状态难以确定等 ;今后的工作应从理论及实验两个方面来解释和解决这些问题。The research progress on electrochemical energy storage, such as electrochemical hydrogen storage, electrochemical lithium ion storage and electrochemical capacitor, with various carbon nano tubes(CNT)was reviewed according to the state of art of the development and application of CNT at home and abroad. The problems in research, including the large potential hysteresis and irreversible capacitance for electrochemical lithium ion storage and the difficulty of determining the existing state of hydrogen in CNT for electrochemical hydrogen storage, are presented. The problems should be explained and solved by both theory and experiment in the future research. CNT, as the electrode of electrochemical capacitor, will be the main application trend in future.
