About Lithium borohydride
Lithium borohydride is a prominent hydrogen storage hydride characterized by its wide-band-gap insulating electronic structure. As a thermodynamically stable compound residing on the convex hull, it represents a highly efficient medium for chemical energy storage applications.
Its significance stems from its high hydrogen density, making it a focal point for research into solid-state fuel systems. The material's robust stability profile and structural diversity, evidenced by numerous reported configurations, underscore its potential for advanced hydrogen delivery technologies.
Key Properties
Cross-validated computational properties for Lithium borohydride, 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.
