Abstract
A cathode assembly for use in a Hall-Heroult electrolytic cell, the assembly including a cathode block which receives two primary cathode collector bars and one secondary cathode collector bar disposed therebetween. The primary collector bars each have an electrical interface with the cathode block which is sized to be equal to or greater than an electrical interface between the secondary collector bar and the cathode block. The primary collector bars are electrically connected to the cathode block only along an interior portion of the cathode block and the secondary collector bar is fully connected to the cathode block. This arrangement improves current distribution through the cathode assembly by minimizing the amount of current passing through the ends of the cathode block.
