Beschreibung
Zusammenfassung:	An electrode for use in an electrolysis process for production of aluminium, the electrode (3, 20) comprises a body of calcinated carbonaceous material connected with an electrical current lead (1, 21). The current lead is embedded in a recess in said carbonaceous body. The recess is wider than the lead and being filled with an electric conductive material. The electric conductive material comprises conductive particles (4, 4'). The method relates to the production of such an electrode and recovery of the conductive material after the electrode has been worn out.
