Cathodic polarization of sulfur in molten salts
As a continuation of studies on the electrochemical behavior of sulfur in molten salts, this paper reports work on the determination of lithium and potassium ion discharge potentials at a sulfur electrode during cathodic polarization in molten LiNO/sub 3/-LiNO/sub 2/-LiOH and LiNO/sub 3/-KNO/sub 3/ at 423/sup 0/K as well as in molten LiF-LiCl-LiI and LiC1-KC1 ay 650/sup 0/K. The studies were carried out by taking polarization curves in a pulsed galvanostatic mode using a three-electrode electrochemical cell. The sulfur electrode floating on the molten salt electrolyte contacted a 5-mm-diameter graphite rod that also touched the molten salt. The same patterns were observed for the cathodic polarization of sulfur in both halide and nitrate melts.
