· JVASP-15204· YMgNi4

YMgNi4 is an intermetallic compound combining yttrium, magnesium, and nickel, belonging to the rare-earth metal hydride storage alloy family. This material is primarily studied for hydrogen storage applications and energy conversion systems, where it exhibits the ability to reversibly absorb and release hydrogen—a property valuable for clean energy technologies. While not yet widely deployed in mass-production engineering, YMgNi4 represents an active research focus in advanced battery materials and hydrogen fuel cell support systems due to its potential to improve energy density and cycle life compared to conventional metal hydrides.
