SmMg2Ni9
metal· JVASP-56230· SmMg2Ni9
SmMg2Ni9 is an intermetallic compound in the samarium-magnesium-nickel system, combining rare-earth and transition metals to form a complex crystalline structure. This material is primarily of research interest in hydrogen storage and battery applications, where the intermetallic phase can reversibly absorb and release hydrogen, making it a candidate for advanced energy storage systems and metal hydride technologies. Compared to conventional nickel-metal hydride formulations, rare-earth intermetallics like SmMg2Ni9 offer the potential for improved cycle life and modified thermodynamic properties, though commercial deployment remains limited and development is ongoing in academic and specialized industrial settings.
