Anodic behavior of lithium in a melt of a eutectic of lithium, potassium, and sodium nitrates
Despite the importance of the problem of the anodic behavior of lithium in a melt of alkali metal nitrates, the kinetics and mechanism of this reaction had, according to the authors, been insufficiently studied. In this work, the anodic oxidation of lithium in a melt of a eutectic of the nitrates of lithium, sodium, and potassium at the temperature 423/sup 0/K by galvanostatic, potentiostatic, and potentiodynamic nonsteady-state methods. The electrochemical experiment, as well as an analysis of the phase diagram of the triple nitrate eutectic, showed that in the case of intensive anodic dissolution of lithium, enrichment of the layer near the electrode with lithium nitrate and its precipitation in the form of a solid salt film on the electrode are possible. At 423/sup 0/K, the first crystals of LiNO/sub 3/ may appear when its concentration is increased by 20%, which, according to the authors, is very realistic in the scale of the thin diffusion layer.
