Li8 U4 O16

Li₈U₄O₁₆ is a mixed-valence uranium-lithium oxide ceramic compound that combines lithium ion conductivity with uranium's redox chemistry, placing it in the family of advanced ionic conductors and nuclear fuel-related materials. This is primarily a research compound of interest in solid electrolyte development and nuclear materials science rather than a widely commercialized engineering ceramic. Potential applications focus on solid-state battery electrolytes leveraging lithium-ion transport, and as a model compound for understanding uranium oxide chemistry in advanced reactor fuels and waste forms; its notable feature is the combination of two normally incompatible functionalities (high Li-ion mobility and uranium valence states) in a single phase.
