Abstract Scope |
Bismuth has been investigated as a potential liquid electrode for molten salt electrorefining, but its electrochemical behavior has received scant attention in eutectic LiCl-KCl melts and no studies were found in the ternary LiCl-KCl-CaCl2 melts. LiCl-KCl-CaCl2 melts offer some advantages over eutectic LiCl-KCl, such as lower melting point and higher oxide solubility. To better understand bismuth’s electrochemical parameters, electrochemical techniques such as cyclic voltammetry, square wave voltammetry, and electrochemical impedance spectroscopy will be used to measure electrochemical parameters, such as diffusivity, exchange current density, standard reduction potential. While the effect of deposition has been well characterized for cyclic and square wave voltammetry, electrochemical impedance spectroscopy has largely been used in soluble-soluble systems. This study aims to see if electrochemical impedance spectroscopy can be used in systems with deposition to measure any of the above parameters while also identifying possible differences or challenges in calculating parameters. |
