Thermal Stability of FeS2 Cathode Material in “Thermal” Batteries: Effect of Dissolved Oxides in Molten Salt Electrolytes

The thermal stability of FeS2 cathode material for thermal batteries is investigated in the LiCl-KCl eutectic containing up to 10 wt% Li2O (used as anti-peak). The results show that the decomposition of pyrite shifts to higher temperatures in the presence of molten salts as the S2 gas is repressed by the liquid phase. For high lithium oxide contents the decomposition temperature of pyrite decreases by 100 °C. In addition Li2FeS2 as reaction product is evidenced whereas Li3Fe2S4 is expected from literature data.

Keywords : Thermal Batteries; Electrolyte; Pyrite; Oxide; Molten Salt; LiCl-KCl Eutectic
