Its position as a near-hull phase suggests it is a viable candidate for synthesis and further experimental investigation in materials science research. The compound is of significant interest for its role in energy storage systems, where its electronic properties and ability to accommodate lithium ions are leveraged to facilitate efficient charge transport and structural stability during electrochemical cycling.
Key Properties
Cross-validated computational properties for LiV2O5, 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.

Reported Structures
Lowest-energy structures reported for LiV2O5, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.

How It Compares
Within the lithium oxides class.
Within the diverse class of lithium oxides, LiV2O5 occupies a distinct niche compared to well-established cathode materials like LiCoO2 or LiMn2O4. While those oxides are widely utilized for their robust performance in commercial batteries, LiV2O5 offers a different structural framework and electronic profile, sharing more in common with the complex vanadium-based oxide LiV3O8 in terms of its potential for multi-valent ion intercalation and flexible lattice dynamics.
