Selenium(IV) Cathode in Molten Chloroaluminates
During the last few years we have been concerned with the electrochemical characterization of several potential cathodes for batteries using molten sodium tetrachloroaluminates (AlCl3-NaCl mixtures) as solvents and aluminum or sodium anodes1–5. The most promising cathode system found was that involving sulfur cations with formal oxidation states ranging from +4 (S(IV)) to 1/8(S16 2+).
