Y2 H6

Y2H6 is a rare-earth metal hydride compound belonging to the family of hydrogen-storage materials and ionic hydrides, where yttrium combines with hydrogen in a stable crystalline structure. This material is primarily of research interest for hydrogen storage systems, solid-state battery applications, and advanced thermal management, as rare-earth hydrides offer potential advantages in energy density and thermal conductivity compared to conventional hydride alternatives. Y2H6 remains largely experimental; its development is driven by the emerging need for dense hydrogen storage in fuel-cell vehicles and the search for improved electrolyte materials in next-generation solid-state batteries.
