Calcined Coke Applications Face Shifting Demand Landscape

The primary traditional applications for calcined petroleum coke are undergoing a period of adjustment, marked by stable demand in core areas but a notable shift between old and new growth drivers. While its role in the electrolytic aluminum industry remains solid, the steel and new energy sectors are creating divergent market trends.

The largest segment for calcined petroleum coke is the manufacture of prebaked anodes for electrolytic aluminum production, accounting for 60% to over 75% of the market. Modest expansion in global aluminum smelting capacity provides a stable demand foundation. However, this mature market is experiencing steady rather than explosive growth, with a growing emphasis on high-quality coke with consistent specifications driven by smelters' focus on energy efficiency and cell stability.

In contrast, sectors linked to the steel industry, such as graphite electrodes and carburizers, are facing weak demand. This is attributed to squeezed profit margins and low operating rates among downstream steel mills, particularly those using electric arc furnaces. For instance, the average operating rate in the graphite electrode industry was only 29.85% in the first half of 2025.

The significant growth area is anode materials for lithium-ion batteries, driven by the boom in the new energy vehicle industry. Anode material production surged by 32.19% year-on-year in the first half of 2025, substantially boosting calcined petroleum coke consumption. Projections indicate that by 2029, anode materials could account for around 10% of calcined petroleum coke consumption, becoming a key driver of overall market demand.
