Aluminum chloride electrolysis has gradually gained attention due to its ability to achieve CO2 free emissions. However, the conventional aluminum chloride electrolysis technology using carbon anodes requires the use of high-purity, low oxygen content anhydrous aluminum chloride, resulting in high cost and difficulty in industrial application. Due to the higher decomposition voltage of alumina under inert anode conditions compared to aluminum chloride, using inert anodes for aluminum chloride electrolysis was expected to relax the demand for oxygen content in anhydrous aluminum chloride, thereby reducing the preparation cost.Static corrosion resistance test and 20A aluminum chloride electrolysis test with cermet inert anodes were conducted using chloride electrolyte and alumina corundum crucibles. The results showed that cermet inert anodes had good corrosion resistance in chloride electrolyte melt, and a certain amount of oxygen element or alumina in aluminum chloride was allowed during the electrolysis process. |
