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.
