Lithium ruthenate

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]
