Research progress on electrochemical energy storage with carbon nano-tubes

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.
