CHEMICAL STABILITY OF SODIUM BETA double prime -ALUMINA ELECTROLYTE IN SULFUR/SODIUM POLYSULFIDE MELTS.

Article abstract of DOI:10.1149/1.2095734

Immersion of sodium beta double prime -alumina electrolyte in sodium polysulfide and pure sulfur melts, at Na/S Battery operation temperatures, showed that the electrolyte was chemically attacked by the melts,and that the extent of degradation was affected by a number of factors, including surface morphology and chemistry of the electrolyte, melt composition, impurity contamination, etc. The corrsosion reactions mostly initiated and concentrated on defected areas, and were catalyzed by the presence of impurities such as water, moist air, oxygen, etc. The corrosion power of sodium polysulfide melts increased with the sulfur content in the range of Na//2S//2 to Na//2S//5.
