The material of the EIS-based sensor was optimized in this study to monitor the in-situ electrolyte layer thickness (hs) under marine atmosphere. It was found that using easy-corrosion materials could introduce high-frequency dispersion in EIS curves and cause unpredictable changes in electrolyte conductivity, leading to inaccurate measurement of hs. However, a Ni sensor with a thin and corrosion-resistant oxide film could eliminate these distractions and achieve accurate hs response in dynamic environments. Finally, methods for optimizing EIS-based sensor were summarized, providing a new approach for hs monitoring.
In this work, the material of the electrochemical impedance spectroscopy based (EIS-based) sensor was optimized to achieve in-situ electrolyte layer thickness (hs) monitoring under marine atmosphere. Results show that the sensor made by easy-corrosion materials not only can induce the high-frequency dispersion in EIS curves, but also cause unpredictable evolution of electrolyte conductivity, leading to an inaccurate measurement of hs. Nevertheless, the Ni sensor with a thin and corrosion-resistant oxide film can eliminate those distractions and achieve accurate hs response in dynamic environments. Finally, methods for optimizing EIS-based sensor were summarized, which paves a new way for hs monitoring.
