· JVASP-55733· K2NaAlH6

K2NaAlH6 is a complex metal hydride compound belonging to the family of lightweight metallic hydrides, which are materials of significant research interest for hydrogen storage and energy applications. This compound is primarily investigated in the context of solid-state hydrogen storage systems, where it serves as a potential candidate for storing and releasing hydrogen under controlled conditions. Its appeal lies in its low density and the reversible nature of hydrogen absorption-desorption cycles, making it relevant for emerging energy technologies rather than conventional structural or industrial applications.
