Abstract:
The present invention relates to a manufacturing method of silicon nanotubes and, more specifically, to a manufacturing method for silicon nanotubes comprising: a step (step 1) of preparing an electrolyte solution by dissolving silane-based compounds and electrolytic salt in an organic solvent; a step (step 2) of depositing electrode materials on one side of a template; and a step (step 3) of forming silicon nanotubes by putting the electrolyte solution prepared in the step 1 and using an electrochemical reduction method after arranging the template in which the electrode materials manufactured in the step 2 are deposited, as a working electrode in an electrolytic bath equipped with a reference electrode and an auxiliary electrode. The manufacturing method of the silicon nanotubes according to the present invention is able to produce a large number of silicon nanotubes by using an electrochemical reduction method with a relatively simple apparatus and facility. Additionally, the silicon nanotubes manufactured thereby easily receive stress according to volume expansion generated during charging and discharging by having large surface areas as compared with existing silicon nanotubes and are usefully used as negative electrode materials of a high capacity secondary battery by exhibiting high charge and discharge capacities as compared with existing carbon-based negative materials.
