摘要： A carbon body, in particular a prebaked anode of an electrolytic cell for the production of aluminum by the electrolysis of alumina in a molten fluoride electrolyte, is treated over its surfaces to improve the resistance thereof to deterioration during operation of the cell by air and oxidizing gases released at the anode, by immersing the body in a treating liquid containing a soluble boron compound and at least one aluminum compound and/or at least one calcium compound as a powder, suspension or colloid or in solution, e.g. at 80.degree. to 120.degree. C. The same treatment can also be applied to a carbon mass forming a Soderberg anode and to cell sidewalls. The addition of the aluminum and/or calcium compound(s) increases strength and improves oxidation resistance compared to impregnation with boric acid alone.

摘要： An electrolysis cell for the production of aluminum by the electrolysis of alumina dissolved in a molten halide electrolyte using a multimonopolar arrangement of substantially non-consumable anodes and cathodes with facing operative surfaces which are upright or at a slope and are spaced in a substantially parallel relationship, enabling operation at low and/or current density with an acceptable production per unit self-lowered area. The operative surface area of the anodes and the cathodes is high due to their upright sloping configuration. Operative surfaces of the anodes and possibly of the cathodes can be increased by making them porous, preferably with their articulated skeletal structure, e.g. with a porous active part on opposite faces of a central current feeder. There is an upward circulation of electrolyte by gas lift between the electrodes, such circulation being enhanced by electrolyte circulation guide means provides by members of electrically non-conducting material arranged outside the spacing between the anodes and the cathodes.

Particles are extracted from the particulate electrode and are subjected to elutriation, the flow of elutriating fluid being such that particles larger than a predetermined size settle against the flow of fluid, while the other particles are carried along by the elutriating fluid and are eventually returned to the electrochemical cell.

摘要： Electric storage batteries with titanium or other film forming metal anodes and cathodes are provided. The anodes are coated with mixed oxide coatings of a film forming metal oxide containing a platinum group metal oxide catalyst, which coatings may contain oxides of other metals to alter the breakdown voltage and increase the oxygen overpotential of the cathodes while preserving a low bromine and chlorine overpotential. The cathodes may be uncoated titanium or other film forming metals or film forming metals with a silver coating thereon. Bipolar film forming metal cathodes and anodes are provided carrying a mixed oxide coating on the cathodic face and either no coating or a silver coating on the anodic face. The invention is applicable to all types of electric storage batteries, either primary or secondary, and multiple batteries may be connected in series or in parallel to provide the desired amperage and voltage characteristics.
