Abstract

A method for producing an anode for a lithium-ion battery includes providing an anode collector carrier film and applying a coating compound onto at least one main surface of the anode collector carrier film. The coating compound contains a particulate auxiliary material. The coating compound is subsequently compressed to form an anode film on the anode collector carrier film. During the compression of the coating compound, the anode collector carrier film is perforated. A lithium-ion battery is also described.
