Electrolytically coated cold rolled strip, preferably for use for the production of battery sleeves, as well as a process for the coating of the same

摘要

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 are added to the electrolyte during coating that produce decomposition products, said decomposition products 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.
