Lithium cobalt oxide

Lithium cobalt oxide is a chemical compound. Its chemical formula is LiCoO₂. It is sometimes called lithium cobaltate or lithium cobaltite. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid. It is commonly used in the positive electrodes of lithium-ion batteries.

Preparation

Lithium cobalt oxide can be made by heating a stoichiometric mixture of lithium carbonate and cobalt(II,III) oxide or metallic cobalt at 600–800°C, then annealing it at 900°C for many hours, all under an oxygen atmosphere.
