Thermal Stability of Lithiated Vanadium Oxide (LVO), Gamma-Lithium Vanadium Bronze (Gamma-LiV2O5) and Vanadium Dioxide (VO2) Thermal Battery Cathode Materials,

Abstract

Thermal analysis of LVO has shown that it has limited thermal stability, possibly accounting for the failure of some thermal batteries with LVO cathodes. Its minor component, gamma-LiV2O5, melts at temperatures which could be reached during thermal battery activation. The major component of LVO, VO2, is thermally stable on its own, but can react with lithium chloride- potassium chloride binary eutectic when heated for prolonged periods above 700 deg C, though VO2/binary eutectic mixtures should be sufficiently stable for use in thermal batteries. Thermal battery cathode.
