CARBON NANOTUBE MANUFACTURING METHOD FOR SUPER-CAPACITOR AND A SUPER-CAPACITOR INCLUDING THEREOF CAPABLE OF OBTAINING SUPER-CAPACITOR INCLUDING CARBON NANOTUBE ELECTRODE WITH A SUPERIOR ELECTROCHEMICAL CHARACTERISTIC

摘要

PURPOSE: A carbon nanotube manufacturing method for super-capacitor and a super-capacitor including thereof are provided to increase energy density and manufacture carbon nanotube with a superior super-capacitor property by directly growing on a conductive substrate without an insulator.;CONSTITUTION: A carbon nanotube manufacturing method for super-capacitor comprises the following steps: evaporating double catalyst layer of iron and aluminum on carbon paper or tantalum substrate; increasing temperature to 600-1000deg.C while spilling argon and hydrogen on the substrate; and supplying carbon with steam. A manufacturing method of the carbon nanotube for super-capacitor additionally includes a step of electrochemically oxidizing carbon nanotube which is directly grown on the conductive substrate in order to increase super-capacitor property. In the aqueous solution of the carbon nanotube for super-capacitor, electrostatic capacity per mass is 40-60F/g. In electro oxidation processing cases, the electrostatic capacity per mass is 150-250F/g in the aqueous solution.;COPYRIGHT KIPO 2012
