| Abstract Scope |
Electrolytic copper foil, a cornerstone material in the electronics and lithium-ion battery industries, whose properties rely heavily on the performance of its electrolytic cell electrodes. The anode plate, responsible for catalyzing the oxygen evolution reaction, and the cathode roller where copper ion deposits, are pivotal components. Currently, the industry predominantly uses iridium-tantalum-titanium anodes with a typical service life of less than one year due to corrosion, and titanium-based cathode rollers that require periodic polishing to remove surface oxides. The integrity and functionality of these electrodes directly govern the quality of the produced copper foil.
To address electrode corrosion and durability in electrolytic cells, by continuously and simultaneously monitoring the potential and impedance changes at both electrodes, the proposed method offers a direct means of assessing electrode failure and can be adapted into on-site process protocols the production of high-quality copper foil. |
