PURPOSE: An apparatus for coating carbon coating liquid on a current collector for a lithium secondary battery is provided to uniformly coat the carbon coating liquid across the current collector, and to adjust the thickness of carbon coating film. CONSTITUTION: The apparatus for coating carbon coating liquid on a current collector(15) for a lithium secondary battery consists of a carbon coating liquid spray device, a roller(19) for guiding the current collector to the top side of the spray device, a screening device installed under the current collector for preventing the carbon coating film from being applied on a tap region of the current collector, and a drier(13) for drying the carbon coating film. The spray device is comprised of a carbon coating liquid reservoir(25), and a nozzle(29) for injecting the carbon coating liquid compressed by a pump(27). The screening device is comprised of a circulating belt screen(35) having a width same with the length of the tab, a roller(37) for supporting and continuously circulating the belt screen, and a cleaning solution tank(41) for cleaning the belt screen. |
