SYSTEM AND METHOD FOR MANUFACTURING SECONDARY BATTERY ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2019/017619

Kind Code:

A1

Abstract:

The present invention relates to a secondary battery electrode manufacturing system for manufacturing an electrode and comprises: a supply roller for supplying a long sheet-shaped current collector; an electrode active material coating device for manufacturing an unfinished electrode by coating a surface of the current collector, which is supplied by the supply roller, with an electrode active material; a rolling roller for rolling the surface of the unfinished electrode and adjusting the thickness of the electrode active material so as to manufacture a finished electrode; and an electrode quality inspection device for inspecting the quality of the electrode through a surface roughness value of the rolling roller and a surface roughness value of the electrode.
