Abstract
The invention relates to a method for roughening the surface of a metal sheet used as electrode support in industrial electrochemical applications, and an electrode made by such method. Mechanical roughening is imparted by skin-passing the sheet between two rollers of a rolling mill, at least one of which is patterned according to a predetermined profile to be transferred by compression to the surface of the metal sheet.
