Cathodes for aluminium electrolysis cells consisting of cathode blocks and current collector bars attached to those blocks whereas the cathode slots receiving the collector bar have a higher depth at the center than at both lateral edges of the cathode block. Additionally, the collector bar thickness is higher at the center than at both lateral edges of the cathode block. This cathode design provides a more even current distribution and, thus, a longer useful lifetime of such cathodes and increased cell productivity. |
