The invention relates to sheet metal packaging products, in particular tinplate or electrolytically chrome-plated sheet steel (ECCS), consisting of a sheet steel substrate (S) with a thickness in the region of 0.1 mm to 0.6 mm and a coating (B), in particular made of tin and/or chromium or chromium and chromium oxide, that is electrolytically deposited on at least one side of the sheet metal substrate. In addition, at least one surface of the sheet metal packaging product provided with the coating (B) has a surface profile with periodically repeating structure elements in at least one direction, wherein an autocorrelation function resulting from the surface profile has a plurality of side lobes with a height of at least 20%, preferably at least 30% of the height of the main lobe. These sheet metal packaging products have improved and novel surface properties.

An apparatus and method for plating magnetic cores by periodically transferring a plate directly back and forth between a metal plating environment and an insulation deposit environment. This direct metal to insulation to metal plating is enabled by a nano-scale insulation layer that provides an imperfect coverage of the metal layer while still keeping sufficient insulation to prevent eddy current formation—even during high-frequency current applications. Therefore, this invention enables the practical creation of magnetic cores having layers with widths even under one nanometer and can generate cores having a layer scale that can be varied to suit a variety of uses in the microelectronic industry.

The present invention provides a zinc battery anode that includes a first layer of zinc foil. An electroplated zinc seed layer is formed on the first layer of zinc foil, the electroplated zinc seed layer having a thickness in a range of 0.01 to 2 microns. The invention further provides a method for forming a seed layer on a zinc battery anode. In the process, the zinc seed layer is deposited on a zinc foil battery anode by electrochemical deposition from a zinc ion-containing solution at a current density of approximately 20 mA cm.sup.−2 to 100 mA cm.sup.−2 to form a uniform and dense seed layer. Through use of a seed layer on the zinc anode, dendrite formation is prevented and long battery life is demonstrated.
