Decomposition mechanisms of some lithium ionic conductors

The decomposition reactions of some lithium ionic conductors are investigated. With many ternary lithium oxides as e.g. LiREO 2 (RE: rare-earth metal) or Li 3InO 3, hydrolysis in air is observed.

Description
Summary:The decomposition reactions of some lithium ionic conductors are investigated. With many ternary lithium oxides as e.g. LiREO 2 (RE: rare-earth metal) or Li 3InO 3, hydrolysis in air is observed. The very steep increase in conductivity at temperatures of ≈380°C is due to the presence of impurities at the surface of the grains. These impurities are generated by hydrolysis. An investigation of the stability of LiAlO phases against molten lithium showed that all these compounds except Li 5AlO 4 exhibited a severe reaction with the molten alkali metal. LiAl may be identified as a reaction product.
