The 4.72% CAGR is not driven by a single factor, but by a dual-engine model:
Engine One: The solid base of aluminum prebake anodes continues to expand. The largest downstream application of calcined petroleum coke (approximately 81% of total demand) remains prebake anodes for aluminum electrolysis. Global primary aluminum output is growing steadily — driven by automotive lightweighting, solar panel frames, and new energy infrastructure. The Asia-Pacific region accounts for roughly 72% of global market share, and capacity expansions in China, India, and the Middle East directly fuel rigid demand for anode-grade calcined coke. This is the “stable” wheel.
Engine Two: The explosive增量 from lithium-ion battery anode materials. This is the critical variable that lifts the growth rate from the traditional 2.8%–3% to 4.72%. The primary raw material for artificial graphite anodes is low-sulfur calcined petroleum coke. The global low-sulfur calcined coke market was approximately USD 1.259 billion in 2024 and is projected to reach USD 1.763 billion by 2031, at a CAGR of roughly 5.0% — outpacing the overall market. As new energy vehicle penetration continues to climb and energy storage projects scale up, anode manufacturers are integrating upstream to secure supply chains, transforming low-sulfur calcined coke from a “metallurgical byproduct” into a “new energy strategic raw material.”
In summary: The aluminum industry provides a certain foundation, while lithium battery anodes deliver high-elasticity incremental demand. Only the combination of both can sustain the 4.72% compound growth rate. If it relied solely on aluminum, the growth rate would likely remain around 3%; it is the battery materials second growth pole that raises the ceiling by nearly two percentage points.
