Effects of synthesis condition of graphitic nanocabon tube on anodic property of Li-ion rechargeable battery

Effects preparation condition of multiwall carbon nanotube on Li intercalat ion were investigated in this study. Both Li intercalation and reversible c apacities increased with increasing contact time of CH4 on Ni catalyst when the multiwall carbon nanotube was prepared. Raman spectroscopy suggested t hat the content of graphitic carbon tube increased with increasing the cont act time of CH4 upon synthesis. Therefore, in case of tubular carbon, graph itic carbon also exhibited a larger capacity for Li intercalation comparing with that of amorphous one. Intercalation and reversible capacity for Li i nsertion at first cycle were attained to a value of 430 and 320 mAh/g, resp ectively, on the carbon nanotube obtained at the contact time higher than 1 00 g-cat h/mol.
