A non-carbon metal-based anode of a cell for the electrowinning of aluminium comprising an electrically conductive metal substrate resistant to high temperature, the surface of which becomes passive and substantially inert to the electrolyte, and a coating adherent to the metal substrate making the surface of the anode electrochemically active for the oxidation of oxygen ions present at the electrolyte interface. The substrate metal may be selected from nickel, cobalt, chromium, molybdenum, tantalum and the Lanthanide series. The active constituents of the coating are for example oxides such as spinels or perovskites, oxyfluorides, phosphides or carbides, in particular ferrites. The active constituents may be coated onto the substrate from a slurry or suspension containing colloidal material and the electrochemically active material.

Anode métallique exempte de carbone pour une cellule d'extraction électrolytique d'aluminium, qui comporte un substrat métallique électriquement conducteur résistant aux hautes températures, dont la surface devient passive et pratiquement inerte à l'électrolyte, et un revêtement qui adhère au substrat métallique et qui rend la surface de l'anode électrochimiquement active pour l'oxydation des ions d'oxygène présents au niveau de l'interface de l'électrolyte. Le substrat métallique peut être choisi parmi nickel, cobalt, chrome, molybdène, tantale et la série des lanthanides. Les constituants actifs du revêtement sont par exemple des oxydes tels que des spinelles ou pérovskites, des oxyfluorures, des phosphures ou carbures, en particulier des ferrites. Les constituants actifs peuvent être déposés sur le substrat à partir d'un coulis ou d'une suspension contenant de la matière colloïdale et la matière électrochimiquement active.
