· JVASP-18464· Li4H4Rh

Li₄H₄Rh is an experimental metal hydride ceramic compound containing lithium, hydrogen, and rhodium. This material belongs to the family of complex metal hydrides, which are research compounds being investigated for hydrogen storage, energy conversion, and advanced catalytic applications. As a research-phase material rather than a production ceramic, Li₄H₄Rh represents exploratory work in high-energy-density materials and represents potential future applications in hydrogen economy technologies, though it remains primarily a laboratory compound without established commercial use.
