| 초록 | From a practical viewpoint, carbon nanotubes (CNT) have been actively studied for various potential applications in a wide range of areas. Among these, energy conversion or storage systems have attracted much attention because CNT have high surface to volume ratios as well as inner space which can be used as a container. For instance, entangled nanotube mats have already been tried to get a high battery performance. Recently it is suggested that if we make vertical nanostructures we can maximize the electrochemical properties and develop to 3-dimensional electrochemical devices. From the background, we here report direct growth of vertically aligned (VA) CNT on commercial copper foil using thermal chemical vapor deposition and present the feasibility of possible applications as anode materials of lithium ion batteries. The nanotubes were vertically grown on the copper foil covered with catalytic films and alumina layer. The tube length was controlled by changing the catalyst film thickness and growth time. The smaller diameters of the grown tubes are expected to have higher take up of lithium ion than those of usual thicker CNT. |
