1. A method for producing an anode for a lithium-ion battery, the method comprising:
providing an anode collector carrier foil;
applying a coating compound comprising a particulate auxiliary material to at least one main face of the anode collector carrier foil, the particulate auxiliary material being selected from the group consisting of lithium ion conductors, Al2O3, TiO2, B2O3, boehmite, synthetic diamond dust, and combinations thereof; and
compressing the coating compound to form an anode film on the anode collector carrier foil, the anode collector carrier foil being perforated by the particulate auxiliary material during the compression of the coating compound.
