Method of manufacturing electrode current collector for secondary battery and electrode including electrode current collector manufactured using the method

A method of manufacturing a current collector for an electrode for a secondary battery, the method comprising:

• preparing a carbon nanotube (CNT) dispersion by dispersing CNTs in a dispersion solvent;
• forming a CNT film on a water surface by spraying the CNT dispersion onto water;
• forming a CNT coating layer on a metal foil by unwinding the metal foil and passing the metal foil through the water at an angle such that one surface of the metal foil is brought into contact with one end of the CNT film formed on the water surface;
• and
• curing the CNT coating layer by heat treatment while rewinding the metal foil with the CNT coating layer formed thereon.
