Abstract
The present invention relates to a system for manufacturing an electrode for a secondary battery. The system for manufacturing the electrode for the secondary battery comprises a supply roller supplying a collector having a long sheet shape; an electrode active material coating device applying an electrode active material to a surface of the collector supplied by the supply roller to manufacture an unfinished electrode; a rolling roller rolling a surface of the unfinished electrode and adjusting a thickness of the electrode active material to manufacture a finished electrode; and an electrode quality inspection device inspecting quality of the electrode through a surface roughness value of the rolling roller and a surface roughness value of the electrode.
