Abstract: A non-stick electrode comprises an electrode an electrically insulating sheath disposed thereon. The electrically insulating sheath has an opening on a surface of the electrode through which an electrical current is transmitted or received to or from an opposing electrode respectively. The electrode protrudes through the opening in the insulating sheath. An electrically conducting interlayer is disposed on the electrode such that it contacts the electrode at the opening in the electrically insulating sheath. The electrically conducting interlayer comprises a material that decomposes at a temperature that is greater than a temperature of a metal that is liquified on contact with the non-stick electrode.
