ceramic

· LiMgH3

LiMgH₃ is a complex metal hydride ceramic composed of lithium, magnesium, and hydrogen. This compound belongs to the family of hydrogen storage materials and ionic hydrides, which are of primary interest in energy storage research rather than established commercial manufacturing. The material is being investigated for hydrogen storage applications in fuel cell systems and as a potential solid-state hydrogen carrier, offering advantages over conventional gas storage in terms of safety and volumetric density, though it remains largely in the research and development phase.
