Abstract

The dataset contains spectroelectrochemical data generated by a sensor applied to the positive compart-ment of an all-Cu redox flow cell and rotating disk electrode data for the related kinetic study. By exploiting the linear relationship between absorbance and concentration, it is possible to evaluate Cu2+ concentration and dynamic SoC tracking under operating conditions. From the comparison of the Cu2+ concentration cal-culated from electrochemical data and from optical data it is possible to evaluate the critical steps in cell operation. The rotating disk electrode kinetic analysis of the Cu⁺/Cu2+ redox couple allows to redesign the charge/discharge protocol in order to overcome these criticalities. The data was developed under the NextGenerationEU-National Recovery and Resilience Plan (NRRP) “Ecosister” project.
