Abstract
This thesis involves two primary subjects, the first subject is to investigate the mass-production of CNTs/CNFs in laboratory scale. The other subject is to study the electrochemical properties of the as-synthesized CNTs/CNTs for the application in secondary lithium-ionbattery. In the first subject, it is found that hydrogen shows better performance than argon in the CVD process for synthesizing CNTs. Thus, all the experiments in the work proceeded in hydrogen atmosphere. Different precursors might cause morphological variation due to difference in C-C bonding, H/C ratio, and precursor vapor pressure. Besides, both reaction pressure and temperature changed the radial growing rate. Furthermore, this study clarified that the growth of CNTs and CNFs followed different mechanisms by referring collision theoryand phase diagram. The main features of CNTs contain highly-perfect graphitization structure and high specific surface area. Thus, it is expected the CNT anode performed high reversibility as graphite anode and high capacity as hard carbon anode. In the second parts of the study, the electrochemical properties of different CNT/CNF anodes were measured, and theintercalation mechanisms were discussed.
