  • Patent number: 11851742
    Abstract: The present invention provides a vapour deposition method for preparing an amorphous lithium borosilicate compound or doped lithium borosilicate compound, the method comprising: providing a vapour source of each component element of the compound, wherein the vapour sources comprise at least a source of lithium, a source of oxygen, a source of boron and a source of silicon, and, optionally, a source of at least one dopant element; providing a substrate at a temperature of less than about 180° C.; delivering a flow of said lithium, said oxygen, said boron and said silicon, and, optionally, said dopant element, wherein the rate of flow of said oxygen is at least about 8×10?8 m3/s; and co-depositing the component elements from the vapour sources onto the substrate wherein the component elements react on the substrate to form the amorphous compound.
