· NdMgNi4

NdMgNi4 is a rare-earth intermetallic compound belonging to the magnesium-nickel family with neodymium addition, representing a research-phase material rather than a widely commercialized alloy. This compound is investigated primarily in hydrogen storage and battery electrode applications, where the rare-earth addition modifies crystal structure and hydrogen absorption capacity compared to simpler Mg-Ni systems. Interest in this material stems from its potential to improve energy density and kinetic performance in metal-hydride batteries and hydrogen storage systems, though industrial adoption remains limited outside specialized research contexts.
