· JVASP-50462· Li2Zr2O5

Li2Zr2O5 is an inorganic lithium zirconate ceramic compound that combines lithium oxide with zirconium oxide in a dense crystalline structure. This material is primarily investigated in advanced thermal and electrochemical applications, particularly as a solid electrolyte constituent and thermal barrier material in next-generation energy systems. Its notable properties for these roles—including ionic conductivity and thermal stability—position it as a candidate for solid-state battery systems and high-temperature protective coatings, though it remains largely in research and early development stages rather than widespread commercial production.
