Lithium ruthenate, Li2RuO3, is a chemical compound of lithium, ruthenium and oxygen. It has a layered honeycomb crystal structure, and can be prepared by direct calcination of Ru metal and lithium carbonate at ca. 700 °C.[2] It is a potential lithium-ion battery electrode material,[2] though this application is hindered by the high costs of Ru, as compared to the cheaper Li2MnO3 alternative.[3]
