Li5AlO4
Li5AlO4 is a stable, insulating lithium aluminate ceramic used in the study of solid-state battery materials.
About Li5AlO4
Li5AlO4 is a thermodynamically stable lithium aluminate that exists as a wide-gap insulating solid. Its structural integrity on the convex hull makes it a significant subject for researchers studying lithium-rich oxide systems and ion transport mechanisms.
Because of its insulating nature and stable composition, this compound is primarily investigated for its role in solid-state electrolyte development and as a protective coating material in high-energy density battery systems.
Key Properties
Cross-validated computational properties for Li5AlO4, aggregated across 2 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.

How It Compares
Within the layered lithium transition-metal oxides class.
Unlike the active transition-metal-based cathodes such as LiCoO2 or LiNiO2, which are designed for reversible redox cycling, Li5AlO4 serves as a stable, non-redox-active framework component within the broader class of lithium oxides. It shares structural similarities with LiAlO2 but offers a higher lithium content, positioning it as a distinct material for studying lithium-rich environments compared to the manganese-heavy members like LiMn2O4 or Li2MnO3.
