A vapour deposition method for preparing a crystalline lithium-containing transition metal oxide compound comprises providing a vapour source of each component element of the compound, including at least a source of lithium, a source of oxygen, and a source or sources of one or more transition metals; heating a substrate to between substantially 150°C and substantially 450°C; and co-depositing the component elements from the vapour sources onto the heated substrate wherein the component elements react on the substrate to form the crystalline compound. |
