lithium tellurite
Lithium tellurite is a stable, insulating ternary oxide compound containing lithium, tellurium, and oxygen.
About lithium tellurite
Lithium tellurite is a thermodynamically stable member of the lithium oxide class. Characterized as a wide-band-gap insulator, this compound exhibits a robust electronic structure that makes it a subject of interest in materials science research. Its presence on the convex hull indicates high stability under standard conditions. The material is structurally diverse, with numerous reported configurations across major databases. This structural flexibility allows it to serve as a foundational component in studies exploring lithium-based ionic transport and dielectric properties in solid-state systems.
Key Properties
Cross-validated computational properties for lithium tellurite, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the lithium oxides class.
Unlike the highly electrochemically active cathode materials in its class such as LiCoO2 or LiMn2O4, Li2TeO3 functions primarily as a stable insulating oxide. While siblings like Li2O are simple binary oxides, Li2TeO3 incorporates tellurium to create a more complex ternary framework, positioning it as a distinct alternative to structural ceramics like Li2TiO3 or Li4SiO4.
