Li6PBrO5
Li6PBrO5 is a stable, insulating antiperovskite material engineered for use as a solid-state electrolyte in lithium-based battery technologies.
About Li6PBrO5
Li6PBrO5 belongs to the class of antiperovskite lithium conductors, characterized by a stable structural framework that supports ionic mobility. As a wide-band-gap insulator, it is designed to maintain electrical integrity while facilitating the transport of lithium ions within solid-state electrochemical systems.
Its thermodynamic stability on the convex hull makes it a robust candidate for material design in next-generation energy storage. By balancing structural complexity with favorable ionic pathways, this compound contributes to the ongoing development of safer and more efficient battery electrolytes.
Key Properties
Cross-validated computational properties for Li6PBrO5, 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 antiperovskite lithium conductors class.
Within the family of antiperovskite lithium conductors, Li6PBrO5 occupies a distinct position compared to simpler structures like Li3BrO. While many siblings in this class focus on binary or ternary halide-oxide combinations, the inclusion of phosphorus in this composition adds a layer of structural complexity that differentiates its electrochemical behavior from the simpler Li3ClO or Li2BrO variants.
