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. It is a potential lithium-ion battery electrode material, though this application is hindered by the high costs of Ru, as compared to the cheaper Li₂MnO₃ alternative.{{cite book|author1=Yoshio, Masaki |author2=Brodd, Ralph J. |author3=Kozawa, Akiya |title=Lithium-Ion Batteries: Science and Technologies|url=https://books.google.com/books?id=gkYhDYk6ftQC&pg=PA10|date=17 July 2010|publisher=Springer Science & Business Media|isbn=978-0-387-34445-4|page=10}}
