ABSTRACT:
The invention relates to a method for producing an electrolytically coated cold rolled strip, preferably for use in the production of battery sheaths. The cold rolled strip is provided with a cobalt or a cobalt alloy layer by an electrolytic method. The aim of the invention is to provide a battery sheath with low values for the electric contact resistance between the cathode substance of the battery and the inner surface of the battery sheath. To this end, organic substances m added to the electrolyte during coating that produce decomposition products, said decomposition produces and/or reaction products of said decomposition products with other components of the electrolytic bath being deposited on the strip material as a brittle layer along with the cobalt or the cobalt alloy.
