CaHBr
CaHBr is a thermodynamically stable ternary hydride material used in the study and development of solid-state hydrogen storage technologies.
About CaHBr
CaHBr is a distinct member of the hydrogen storage hydride class, characterized by its insulating electronic structure. As a thermodynamically stable phase located on the convex hull, it represents a robust material candidate for chemical hydrogen containment and solid-state storage applications. Its structural integrity makes it a point of interest for researchers investigating stable ternary hydride systems. The material is primarily studied for its potential role in advanced energy storage technologies where stability and hydrogen density are critical factors. By leveraging its unique composition, scientists aim to optimize hydrogen release and uptake cycles in various energy-dense environments.
Key Properties
Cross-validated computational properties for CaHBr, 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.
