YNi5 is an intermetallic compound in the yttrium-nickel system, belonging to a family of rare-earth metal alloys with well-defined crystal structures and notable hydrogen storage and absorption properties. This material is primarily investigated in hydrogen energy storage applications, metal hydride batteries, and thermal energy management systems where its ability to reversibly absorb and release hydrogen makes it valuable for next-generation energy storage devices. Compared to conventional steel or nickel alloys, YNi5 and related rare-earth intermetallics offer superior hydrogen capacity and kinetics, making them of significant interest in research and emerging hydrogen economy technologies, though industrial adoption remains limited to specialized applications.
