· JVASP-152866· Li2MgH4

Li2MgH4 is a complex metal hydride ceramic compound combining lithium, magnesium, and hydrogen. This material is primarily of research interest as a solid-state hydrogen storage medium and energy carrier, with potential applications in hydrogen economy technologies where conventional gas or liquid storage approaches are impractical. Its significance lies in the metal hydride family's capacity to reversibly absorb and release hydrogen at moderate temperatures, making it a candidate for next-generation energy storage systems, though practical engineering deployment remains under development.
