Li3PO4
Lithium phosphate · Lithium orthophosphate
Lithium phosphate is a stable, insulating compound widely studied for its potential as a solid-state electrolyte in high-performance lithium-ion batteries.
About Lithium phosphate
Lithium phosphate is a thermodynamically stable lithium oxide that functions as a wide-band-gap insulator. Its structural integrity and chemical robustness make it a subject of significant interest in materials science, particularly for applications requiring stable ion-conducting pathways.
Researchers utilize this compound primarily as a foundational material in the development of solid-state electrolytes. By serving as a stable host or additive, it helps improve the performance and safety profiles of advanced energy storage systems compared to conventional liquid-based alternatives.
Key Properties
Cross-validated computational properties for Lithium phosphate, 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 lithium oxides class.
Unlike the transition-metal-based lithium oxides such as LiCoO2 or LiNiO2, which are primarily valued for their redox activity and capacity for lithium intercalation in cathode materials, Li3PO4 acts as an insulating structural component. While its siblings are often chosen for their electrochemical potential, Li3PO4 is distinguished by its stability and dielectric properties, positioning it as an essential electrolyte candidate rather than an active cathode material.
