Abstract

The present invention relates to a method for producing a substrate (2) which is coated with an alkali metal (1), in which method a promoter layer (3) which is composed of a material which reacts with the alkali metal (1) by at least partial chemical reduction of the promoter layer (3) is applied to a surface of the substrate (2) and a surface of the promoter layer (3) is acted on by an alkali metal (1) and then the alkali metal (1) is converted into the solid phase and a coating containing the alkali metal is formed.
