Abstract
Official abstract text for this publication.
In one embodiment, the disclosed subject matter relates to an electrolytic cell that has: a cell reservoir; a cathode support retained on a bottom of the cell reservoir, wherein the cathode support contacts at least one of: a metal pad and a molten electrolyte bath within the cell reservoir, wherein the cathode support includes: a body having a support bottom, which is configured to be in communication with the bottom of the electrolysis cell; and a support top, opposite the support bottom, having a cathode attachment area configured to retain a at least one cathode plate therein.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for producing aluminum metal by electrochemical reduction of alumina, comprising: (a) passing current between an anode and a cathode through an electrolytic bath of an electrolytic cell, the cell comprising: (i) a cell reservoir, (ii) a cathode support retained on a bottom of the cell reservoir, wherein the cathode support contacts at least one of: a metal pad and a molten electrolyte bath within the cell reservoir, wherein the cathode support includes: a body having a support bottom, which is configured to be in communication with the bottom of the electrolytic cell; and a support top, opposite the support bottom, having a cathode attachment area configured to retain a at least one cathode plate therein; and (b) feeding a feed material into the electrolytic cell.
