Effects preparation condition of multiwall carbon nanotube on Li intercalation were investigated in this study. Both Li intercalation and reversible capacities increased with increasing contact time of CH₄ on Ni catalyst when the multiwall carbon nanotube was prepared. Raman spectroscopy suggested that the content of graphitic carbon tube increased with increasing the contact time of CH₄ upon synthesis. Therefore, in case of tubular carbon, graphitic carbon also exhibited a larger capacity for Li intercalation comparing with that of amorphous one. Intercalation and reversible capacity for Li insertion at first cycle were attained to a value of 430 and 320mAh/g, respectively, on the carbon nanotube obtained at the contact time higher than 100g-cath/mol.
