Cathodes (1) for aluminium electrolysis cells consisting of cathode blocks (4) and current collector bars (2) attached to those blocks whereas the cathode slots (3) receiving the collector bar are lined with expanded graphite lining (9) thus providing longer useful lifetime of such cathodes and increased cell productivity.
La présente invention concerne des cathodes pour cellules à électrolyse d'aluminium constituées de blocs de cathode et de barres collectrices de courant fixées à ces blocs tandis que les fentes de cathode recevant les barres collectrices sont revêtues d'un revêtement de graphite expansé permettant d'obtenir une durée de vie utile plus longue de telles cathodes et d'augmenter la productivité de la cellule.
