Abstract
Raman EPR and visible absorption spectra of sodium tetrasulfide in the solid state and melts have been studied from room temperature up to 300°C. The above techniques provide strong evidence for breaking of the polysulfide chains resulting in the production of S3-radical ions. The existence of the radical ions in polysulfides at elevated temperatures is important for understanding the electrode processes in sodium sulfur batteries.Keywords
