Abstract:The inert anode is the key technology for the future low-carbon development of aluminium electrolysis industry, which is also an important aspect of the carbon neutrality. In recent years, the significant advances in inert anode material research and engineering have provided new opportunities for the breakthrough in industrial applications. Therefore, this paper presents a comprehensive review of the research progress of inert anode materials in recent years. The following aspects were emphasized, including the formation of the protective film on the metallic anode surface, composition and structure optimization of cermet anode, the improvement of performance of anode materials, and so on. The comparison of the conductivity and corrosion resistance of inert anode materials was discussed, with the aim to provide the prospects of development trend.
Key words: inert anode; aluminium electrolysis; metallic anode; cermet
