About Li2VO3
Li2VO3 is a semiconducting member of the lithium oxide family that occupies a position near the thermodynamic stability hull, suggesting it is a viable candidate for experimental synthesis. Its unique electronic structure makes it an intriguing subject for researchers investigating new pathways for ion transport and electrochemical activity.
As a material with multiple documented structural configurations, it represents a versatile building block within inorganic chemistry. Its potential utility is driven by the interplay between its lithium-rich composition and the redox-active nature of the vanadium centers, which are central to its role in modern materials science.
Key Properties
Cross-validated computational properties for Li2VO3, 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.
