Lithium platinate, Li2PtO3, is a chemical compound of
lithium,
platinum and oxygen. It is a
semiconductor with a layered honeycomb crystal structure and a
band gap of 2.3 eV, and can be prepared by direct
calcination of Pt metal and
lithium carbonate at ca. 600 °C.[3] Lithium platinate is a potential
lithium-ion battery electrode material,[2][4] though this application is hindered by the high costs of Pt, as compared to the cheaper Li2MnO3 alternative.[5]
