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.
