Graphite

Graphite is crystalline carbon, and in a lithium-ion battery it is the anode: the host structure the lithium ions slot into when the cell charges. It comes in two forms that compete directly. Natural graphite is mined, most usefully as flake, then purified and shaped. Synthetic graphite is manufactured by baking petroleum needle coke at extreme temperature, which makes it a downstream product of the oil refining complex covered elsewhere in this book, more expensive and more energy-intensive but purer and more consistent. Roughly speaking, natural is cheaper and synthetic performs better, most anodes blend them, and the mix moves with relative price.

The reason graphite matters strategically is not the mine, it is the processing. Turning flake into battery-grade material means milling it into rounded particles, purifying it to very high carbon content, and coating it, and the output is coated spherical purified graphite. That step is where the concentration lies. China accounts for something over 60 percent of flake mining and about 80 percent of synthetic graphite, but roughly 99 percent of spherical graphite and about 93 percent of finished anode material. A country can open a graphite mine anywhere. Very little of the world can currently turn the rock into an anode.

That chokepoint was made explicit in October 2023, when China announced export permit requirements effective 1 December 2023 covering high-purity synthetic graphite and its products and natural flake graphite and its products, including spherical and expanded graphite. Chinese graphite exports fell sharply in the following months. In October 2025 the controls were widened again to cover lithium battery technology and artificial graphite anode materials. Graphite is therefore the clearest case in the battery complex of an input being used as policy rather than as a commodity, and it is worth noting the sequencing: China restricted graphite before it restricted anything else in the battery chain, because graphite was where its grip was tightest.

The Western response has been tariffs and, more slowly, plants. The United States ran antidumping and countervailing duty investigations into Chinese active anode material, reaching preliminary duties in 2025 and a final determination on 11 February 2026 setting countervailing duties near 67 percent, antidumping duties of 93.5 percent for named companies and 102.72 percent China-wide. Stacked with Section 301, Section 232, and IEEPA tariffs, the effective burden on Chinese anode material entering the US runs to roughly 220 percent. That is not a tariff in the ordinary sense of adjusting a price; it is an instruction to build a supply chain somewhere else. New capacity is being built at Balama in Mozambique and Vidalia in Louisiana among others, but qualifying an anode material into a cell design takes years, so the gap between the policy and the physical supply is measured in battery-development cycles.

It is easy to forget that batteries are the new use. Graphite has long gone into refractories lining steel furnaces and ladles, into graphite electrodes for electric-arc furnace steelmaking (the same electric steel route covered on the steel sheet), and into lubricants, foundry facings, brake linings, and crucibles. Those industrial uses are mature and still large; the battery is what turned a sleepy industrial mineral into a strategic one. This split matters commercially, because refractory-grade and battery-grade graphite are different products with different specifications, and a producer cannot simply redirect one into the other.

The market has no futures contract anywhere and prices are assessed rather than traded, published by price reporting agencies covering flake by mesh size and carbon content, spherical graphite, and anode material. That opacity is normal for a specification-driven mineral, but it produces a striking paradox worth stating plainly: graphite has spent recent years being called one of the most critical materials on earth while its actual price has been weak, because Chinese capacity ran well ahead of demand. Strategic scarcity and commercial glut are not the same thing, and graphite is the cleanest illustration of the difference in this book.
