  • Cathode current collector for a Hall-Heroult cell
    Patent number: 11136682
    Abstract: The invention relates to an electrolytic cell (1) for the production of aluminium (2) including collector bars structure modifications (13,14,15,16) under the cathode (4), namely a copper collector bar held in a U-shaped profile or directly embedded into the cathode. This leads to an optimized current distribution in the liquid aluminium metal (2) and/or inside the carbon cathode allowing for operating the cell at lower voltage. The lower voltage results from either a lower anode to cathode distance (ACD), and/or to lower voltage drop inside the carbon cathode from liquid metal to the end of the collector bar.
    Type: Grant
