TL;DR: In this article, the authors measured the impedance of polarized platinum microelectrodes in the molten salt systems, LiCl-KCl at 400 deg C, 530 deg C. They were of magnitudes consistent with a simple Helmholtz model although the anodic values tend to be high, perhaps because of specific adsorption.
Abstract: lmpedances were measured of polarized platinum microelectrodes in the molten salt systems, LiCl-KCl at 400 deg C, 530 deg C. Frequency dispersion of both the observed resistance and capacitance was evident in all cases, but apparent double layer capacities obtained by extrapolation to infinite frequency were in reasonable accord with some previously reported data. They were of magnitudes consistent with a simple Helmholtz model although the anodic values tend to be high, perhaps because of specific adsorption. Some measurements of faradaic impedance were also made, but these were less successful and the exchange current for the Pt/Pt/sup 2+/ system was high. (auth)
