The solubility of lithium oxide (Li2O) and diffusion coefficient of oxide ions (O2−) has been determined to be 0.83 mol% and 2.1 × 10−6 cm2 s−1, respectively, at 773 K in a LiCl–KCl–CsCl eutectic melt. Cyclic voltammograms show that oxygen (O2) evolution on a boron-doped diamond (BDD) electrode is reversible and carbon dioxide (CO2) evolution on a glassy carbon electrode is irreversible. The standard formal potential of O2/O2− estimated by electromotive force measurements using the BDD electrode is 2.431 V ± 0.001 vs. Li+/Li at 773 K.
