The invention relates to a cathode block for an aluminum electrolytic cell, in particular based on carbon and/or graphite, having at least one groove for accommodating a bus bar, said groove being arranged on one of the sides of the cathode block and extending in the longitudinal direction of the cathode block, wherein at least one section of the surface of the side of the cathode block opposite the side having the at least one groove is curved outwardly in the shape of an arch as viewed in the cross-section of the cathode block, wherein the vertex of the at least one section curved outwardly in the shape of an arch is arranged over the at least one groove, with respect to the direction extending perpendicularly to the side having the at least one groove in the cross-section of the cathode block. The invention further relates to a cathode block for an aluminum electrolytic cell, in particular based on carbon and/or graphite, which cathode block has a tub-shaped surface as viewed in the longitudinal section of the cathode block, wherein the tub has two edge regions and a bottom region, which is arranged between the edge regions and lowered relative to the edge regions as viewed in the longitudinal direction of the cathode, wherein a respective side wall region is provided between each edge region and the bottom region, which side wall region connects the respective edge region and the bottom region, wherein at least one of the two connecting regions between the edge regions and the side wall regions and/or at least one of the two connecting regions between the bottom region and the side wall regions is curved in the shape of an arch, wherein the at least one section curved in the shape of an arch has a length of more than 2 cm. |
