Title: Systems and methods of electrolytic production of aluminum

Abstract

In some embodiments, an exemplary electrolytic cell includes: a cathode structure disposed within an electrolysis cell, wherein the electrolysis cell is configured to produce metal on a surface of the cathode structure, wherein the cathode structure is configured to fit along a floor of the electrolysis cell, wherein the cathode structure has a sloped surface when compared to a generally horizontal plane, and wherein via the sloped surface, the cathode structure is configured to drain a metal product from the sloped surface towards a lower end of the cathode structure.
