Abstract

See full text

In accordance with the instant disclosure, aluminum electrolysis cells having reduced cathode voltage drop and methods of operating the same are provided. More particularly, the instant disclosure provides a compression device for applying a force to an end of the current collector subassembly to improve the contact, thereby reducing the joint resistance across the interface between the cathode block and the current collector subassembly. The compression device is used in conjunction with the systems and methods of the instant disclosure.
