Quantification of the Impact of Residual H2O on Cathodic Behavior in Molten CaCl2 Electrolysis

Communication—The Development of a Stable and Practical Saturated Reference Electrode for Molten Chloride Salt Systems

“…Potentials reported in these figures relative to the Ag/Ag + are consistent with previous measurements in CaCl 2 and the estimation from thermochemical data of −2.17 V vs Ag/Ag + (1 mol %) for Li + /Li. 29,[32][33][34][35] Each RE in CaCl 2 shows more instability than in LiCl due to solubility of Ca metal in molten CaCl 2 (see supplementary material including figure S5). 36 However, even in CaCl 2 , the SREs still show greater stability than Ag/Ag + RE and good replicability to each other.…”

Steam-assisted electro-reduction of NiO: a sustainable alternative to conventional hydrogen reduction

“…29 Moreover, CaCl 2 is also known to possess hygroscopic characteristic, enabling the evolution of hydrogen. 30,31 Therefore, KCl and CaCl 2 were separately added into LiCl molten electrolyte and the reduction of NiO in such electrolytes was studied.…”
