The present invention relates to a metal cathode sheet as component of cathode equipment for an electrolysis tank for the electrolytic recovery of pure metals, especially copper. The cathode sheet is provided, at its side edges which come into contact with the electrolyte and are vertically aligned in the electrolysis tank, with an edge protector, made of a ceramic material. The edge protector is electrically insulating, of dense porosity and resistant to electrolyte. Sharp-edged breakthroughs and the outer cathode cutting edges are completely coated by edge protector. In this manner flux line concentrations at these locations are forestalled.
