Abstract
In a method for producing an anode for a lithium cell, and/or a lithium cell as well as anodes and lithium cells of this type, to extend the service life of the lithium cell and to selectively form a first protective layer including electrolytic decomposition products, on an anode including metallic lithium, a first electrolyte is applied on the anode ex situ, i.e., prior to assembling the lithium cell to be produced. To stabilize the first protective layer, a second protective layer is applied in a subsequent method step.
