In recent years, with the rapid rise of the global new energy industry and the continuous advancement of industrialization, the market demand for aluminum carbon materials—core materials in electrolytic aluminum production—has been steadily climbing.

Aluminum carbon materials are regarded as a crucial cornerstone of the aluminum electrolysis industry. Based on their positions and functional differences within electrolytic cells, they can be divided into two major categories: anode materials and cathode materials.

Pre-baked anodes are typical representatives of anode materials for aluminum carbon. They are carbon blocks with stable geometric shapes, made by roasting aggregates such as petroleum coke and pitch coke, with coal tar pitch as a binder. Pre-baked anodes not only act as conductors but also participate in electrochemical reactions, during which they are consumed. Therefore, the quality of pre-baked anodes has a significant impact on the quality of primary aluminum.

Driven by multiple factors, the global demand for pre-baked anodes has shown a steady growth trend
