· JVASP-55692· K2LiAlH6

K2LiAlH6 is a complex metal hydride compound combining potassium, lithium, and aluminum with hydrogen, belonging to the family of lightweight metal hydrides under active research for energy storage applications. This material is primarily investigated in hydrogen storage research and advanced battery development rather than established industrial production, where its combination of low density and hydrogen-rich composition makes it a candidate for next-generation energy systems. The compound represents the broader class of complex hydrides being explored to overcome limitations of conventional hydrogen storage media and solid-state battery electrolytes.
