Abstract

Three electrochemical methods for finding the exchange current density of materials in molten salt (cyclic voltammetry (CV), linear polarization (LP), and Tafel) were compared to investigate which would provide the optimal near real-time approximation for exchange current density. LaCl₃ was used as the material in a ternary salt system (LaCl₃-LiCl-KCl) and a quaternary salt system (LaCl₃-GdCl₃-LiCl-KCl). Each technique was applied at temperatures ranging from 723K - 798K, as well as various scan rates. The resulting exchange current density values showed CV, LP, and Tafel having mean standard deviations of 0.0019 A cm^-2, 0.0039 A cm^-2, and 0.1065 A cm^-2, respectively. The data showed that CV was the superior method due to its faster scan rate along with possessing the lowest deviation.
