英文摘要: Non-graphitic carbon nanotubes (NGCNTs) are successfully prepared by carbonization of polypyrrole (PPy) nanotubes precursor synthesized via a self-assembly process. It is observed from transmission electron microscopy (TEM) that the diameter and length of the NGCNTs are 100-200nm and 2-10 mu m, respectively. The electrochemical performances of the NGCNTs are evaluated by cyclic voltammograms and galvanostatic discharge-charge cycling. The results show that NGCNTs deliver an initial reversible capacity of 635.7 mAh g(-1) at current density of 100 mA g(-1) with a high capacity retention ratio of 85.7% after 150 cycles. Even up to 4A g(-1), the reversible capacity of NGCNTs remains in 280.1 mAh g(-1). The improved performance of NGCNTs is attributed to the non-graphitic form, tubular morphology and crosslinked conducting networks. Therefore, it is a potential anode material for lithium-ion battery. (C) 2013 Elsevier Ltd. All rights reserved.
