Abstract: Petroleum coke is an important raw material for preparing negative electrode materials for lithium-ion batteries, and its quality has a huge impact on the quality of negative electrode materials for lithium-ion batteries, as well as the safety and cycling stability of the prepared lithium-ion batteries. In recent years, the rapid rise of the new energy industry has driven the rapid growth of demand for lithium-ion battery negative electrode materials. Accelerating the high-quality and green utilization of petroleum coke is necessary to promote the achievement of the dual carbon goal. By understanding the production process of petroleum coke for preparing negative electrode materials, comparing and analyzing the evaluation methods of petroleum coke production enterprises and negative electrode material production enterprises within the system, it is of great significance to break down industry barriers, strengthen upstream and downstream connections, accelerate the construction of production, sales, research and application alliances, and promote the improvement and efficiency of refining enterprises.
