SYSTEMS AND METHODS OF PROTECTING ELECTROLYSIS CELLS

摘要

Broadly, the present disclosure relates to sidewall features (e.g. inner sidewall or hot face) of an electrolysis cell, which protect the sidewall from the electrolytic bath while the cell is in operation (e.g. producing metal in the electrolytic cell).

主权项

1. An apparatus, comprising:
an electrolysis cell is provided, comprising:
an anode;a cathode in spaced relation from the anode;a molten electrolyte bath in liquid communication with the anode and the cathode;a cell body comprising a sidewall and a bottom,
wherein the cell body is configured to retain the molten electrolyte bath;wherein the sidewall comprises:
a polarized sidewall portion, anda non-polarized sidewall portion; wherein the non-polarized sidewall portion is configured to extend out from the sidewall and provide a stepped configuration, wherein the non-polarized sidewall portion comprises a stable material;wherein the polarized sidewall portion and the non-polarized sidewall portion are adjacent to each other and wherein the non-polarized sidewall portion and the polarized sidewall portion are configured in liquid communication with the molten electrolyte bath.
