Abstract

L'invention a pour objet un bloc anodique en carbone pour utilisation dans une cellule d'électrolyse de métal de hauteur H entre une face supérieure (24) et une face inférieure (23) et comprenant sur la face inférieure (23) au moins une rainure (20a) de profondeur p(x) et de longueur Lr, la rainure s 'étendant selon une direction x et ladite profondeur p(x) étant variable le long de ladite direction x, caractérisé en ce que ladite profondeur p(x) varie de façon non-linéaire le long de ladite direction x et en ce que ladite profondeur p(x) est inférieure à une première valeur Z1 sur au moins 60% de la longueur Lr de ladite rainure et est supérieure à une deuxième valeur Z2 au moins égale à Z1 + 10% de la hauteur H sur 3 à 40% de la longueur Lr de la rainure.
