Abstract

Die vorliegende Anmeldung betrifft eine Elektrolysezelle (10) für eine Schmelzflusselektrolyseanlage, insbesondere zur Herstellung von Aluminium, die eine Elektrolytwanne (12) zur Aufnahme eines geschmolzenen Elektrolyten (14) und zumindest zwei Elektroden (16, 18) aufweist, wobei die Elektroden (16, 18) jeweils Oberflächen (16.1...16.4, 18.1...18.4) aufweisen, wobei die Oberflächen (16.1...16.4, 18.1...18.4) einander zugewandt sind, um zwischen sich einen Stromfluss durch den Elektrolyten (14) zu ermöglichen. Erfindungsgemäß ist zumindest eine der Oberflächen (16.1...16.4, 18.1...18.4) schräg zu einer vertikalen Richtung (V) ausgerichtet und sind die zumindest zwei Elektroden (16, 18) beide von oben elektrisch angeschlossen.

The present application relates to an electrolysis cell (10) for a fused-salt electrolysis plant, in particular for the production of aluminum, which has an electrolyte trough (12) for receiving a molten electrolyte (14) and at least two electrodes (16, 18), the electrodes (16, 18) each having surfaces (16.1...16.4, 18.1...18.4), the surfaces (16.1...16.4, 18.1...18.4) facing each other to allow current flow through the electrolyte (14) therebetween to allow. According to the invention, at least one of the surfaces (16.1...16.4, 18.1...18.4) is oriented obliquely to a vertical direction (V) and the at least two electrodes (16, 18) are both electrically connected from above.
