Abstract | A vapour deposition method for preparing an amorphous lithium borosilicate or doped lithium borosilicate compound 29 comprises providing a flow of vapour sources of at least lithium, oxygen, boron and silicon 18, 20, 22, 24 to co-deposit the component elements on a substrate 14, which react to form the amorphous compound, wherein the compound has a lithium content in the range 40 - 65 atomic percent based on the combined atomic percentages of lithium, boron and silicon. The method may be used to form a surface-modified electrode or an electrolyte layer of a battery. The deposited compound may exhibit high ionic conductivity. The lithium vapour source may be provided by heating material in a crucible to generate a flux of material, for example using a Knudsen cell source. The rate of deposition of lithium may be controlled by varying the temperature of the Knudsen source. The silicon and boron vapour sources may be provided using electron gun sources. The vapour source of oxygen may be atomic or molecular oxygen and preferably comprises an oxygen plasma source. |
