Key Properties
Cross-validated computational properties for LiTiFeO4, 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 titanate anodes class.
Within the diverse group of titanate anodes, LiTiFeO4 occupies a unique position compared to more conventional members like Li2TiO3. While many titanates are primarily explored for their lithium-insertion properties, the inclusion of iron in the lattice of LiTiFeO4 introduces distinct electronic characteristics that differentiate it from the simpler alkali-metal titanates such as Na2Ti3O7.
