Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a substrate formed from copper or nickel coated with a lithium layer, wherein a mediator layer comprising copper oxide on a surface of the substrate is chemically formed from copper or a mediator layer comprising nickel oxide on a surface of the substrate is chemically formed from nickel, a surface of the mediator layer is coated with liquid lithium and the mediator layer reacts with the liquid lithium by at least partial chemical reduction wherein the liquid lithium forms a solid phase lithium and a coating of the lithium is formed producing a lithium coated copper foil substrate or lithium coated nickel foil substrate. 2. The method as claimed in claim 1 , wherein the mediator layer reacts when in contact with the lithium of the lithium coating to form a mediating interface or boundary layer. 3. The method as claimed in claim 1 , wherein the mediator layer is formed by thermal oxidation, sputtering, chemical vapor deposition, wet-chemical coating or heat treatment. 4. The method as claimed in claim 1 , wherein the lithium of the lithium layer is applied on the mediator layer by laser melting, melting using a heating apparatus, knife coating, application using a slot die, spraying, spreading, dip coating, thermal spraying or lamination. 5. The method as claimed in claim 1 , wherein the mediator layer is formed with a thickness of between 0.1 nm and 1000 nm before coating with lithium.
