MANUFACTURING METHOD OF CARBON MATERIALS MICROBALL AND MANUFACTURING METHOD OF ELECTRODE BY USING THE MICROBALL

摘要

One embodiment of the present invention includes a first step of preparing a dispersion by injecting a carbon material into a solvent, a second step of preparing a microball by spraying and freezing the dispersion, and a third step of lyophilizing the microball The present invention relates to a manufacturing method of a carbon material microball. According to another embodiment of the present invention, there is provided a method of manufacturing a carbon nanotube, comprising the steps of: heat treating the carbon microbubble in an inert gas atmosphere at 700-1000 占 폚, mixing the heat-treated microball and the binder in a solvent to prepare a slurry, Coating a substrate or a foil, and drying at 200 DEG C or lower.
