Composition gradients in electrolyzed LiCl-KCl melts
Analysis of transport in a mixed electrolyte has previously predicted significant composition gradients in the LiCl-KCl electrolyte of high-temperature Li/S batteries. Composition gradients in quenched electrolyzed LiCl-KCl eutectic are measured with high distance resolution by scanning electron microscopy with energy-dispersive x-ray spectroscopy. The reported results include compositions of LiCl-KCl contained in a porous Y/sub 2/O/sub 3/ matrix and electrolyzed between two solid Li/Al electrodes, and of the electrolyte in the pores of a powdered Li/Al electrode. The results provide quantitative measurements of the composition in the electrolyte, and demonstrate precipitation of LiCl in the porous anode.
