Key Properties
Cross-validated computational properties for LiMn2O3F, 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 layered lithium transition-metal oxides class.
Within the diverse group of layered lithium transition-metal oxides, LiMn2O3F occupies a distinct niche by incorporating fluorine into the lattice. While classic materials like LiCoO2 and LiNiO2 rely on pure oxide frameworks for charge transport, the inclusion of fluorine in LiMn2O3F serves to tune the electronic properties, potentially offering different stability profiles compared to the more common LiMn2O4 spinel or Li2MnO3 layered structures.
