Every lithium-ion battery has two electrodes — a cathode and an anode. The cathode gets the headlines because it contains the expensive metals: lithium, nickel, cobalt, manganese. The anode is graphite. It is graphite in your phone, graphite in your laptop, graphite in every Tesla and every BYD and every grid-scale storage installation on earth. Graphite constitutes more of a lithium-ion battery by weight than lithium does. And China controls approximately 77 percent of natural graphite mining, more than 90 percent of graphite refining into battery-grade spherical graphite, and — as of October 2025 — has placed the entire category under export controls that give Beijing licensing authority over every kilogram that leaves the country. The material that makes the energy transition physically possible is more supply-concentrated than any other battery input, and the country that controls it has spent the last two years demonstrating exactly how willing it is to use that leverage.
Why graphite and why now
Natural graphite is mined. Synthetic graphite is manufactured from petroleum coke at extremely high temperatures. Both end up as anode material in lithium-ion batteries, where graphite’s layered crystal structure allows lithium ions to intercalate — slide between the layers during charging and slide back out during discharge. The process is the fundamental mechanism that makes rechargeable batteries work. Without graphite anodes, there are no lithium-ion batteries. Without lithium-ion batteries, there are no EVs, no grid storage, no portable electronics, no energy transition.
The supply chain has three chokepoints, and China dominates all of them. First, mining: China produces roughly 77 percent of the world’s natural graphite, with Mozambique, Brazil, and Madagascar as distant secondary sources. Second, processing: mined graphite must be purified, shaped into spherical particles, and coated to function as battery-grade anode material. China controls over 90 percent of this processing — a concentration tighter than its grip on rare earth refining. Third, anode manufacturing: the finished anode components that go into battery cells are overwhelmingly produced in China or by Chinese companies operating abroad. Japan sources 90 percent of its graphite from China. South Korea sources 93 percent of its anode materials from Chinese suppliers. The United States is better diversified on raw graphite imports — 33 percent from China, 21 percent from Mexico, 17 percent from Canada — but on processed battery-grade material, the dependency is nearly as severe.
The export control escalation
China’s graphite weaponization has followed the same playbook it used with gallium and germanium: announce controls, let the market panic, then selectively enforce to maintain leverage without fully cutting supply. The timeline tells the story.
In October 2023, China imposed export permit requirements on natural graphite — both flake graphite and spherical graphite — citing national security. The move was widely interpreted as retaliation for U.S. semiconductor export controls. Export volumes initially dropped but partially recovered as licenses were granted selectively, demonstrating that the controls were a valve, not a wall.
In October 2025, Beijing escalated dramatically. New export controls effective November 8 expanded the scope to include synthetic (artificial) graphite anode materials, blended graphite anodes, cathode material precursors, high-performance lithium-ion batteries with energy density above 300 watt-hours per kilogram, and — critically — the manufacturing equipment and production technologies required to make all of these things. This wasn’t just restricting the finished product. It was restricting the ability to build the factories that produce the product. Graphitization furnaces, CVD rotary kilns, spray dryers, coating equipment — all now require export licenses. The IEA’s analysis was blunt: these controls “target some critical chokepoints in global battery supply chains” for which “supply options outside China are extremely limited.”
Then, in November 2025, Beijing temporarily suspended the stricter end-user verification requirements for graphite shipments to the United States, valid through November 2026. The suspension aligned with bilateral trade consultations and followed the pattern China has established with rare earths: tighten, negotiate, offer temporary relief, preserve the structural leverage for future use. The November 2026 expiration date isn’t a formality. It’s a countdown.
The IRA collision
The U.S. Inflation Reduction Act created an additional problem that China’s export controls have now weaponized. To qualify for the full $7,500 EV consumer tax credit, manufacturers must demonstrate that critical minerals in their batteries meet “foreign entity of concern” (FEOC) rules — effectively limiting Chinese content in qualifying battery supply chains. The FEOC requirement for graphite was initially exempted until the end of 2026 because the supply chain was so concentrated that enforcing it immediately would have disqualified virtually every EV sold in America.
Manufacturers scrambled for compliant sources. Several identified BTR — a Chinese graphite company planning to source from Indonesia or Morocco — as a workaround. In January 2025, the Department of Energy classified BTR as a foreign entity of concern and extended that designation to its overseas subsidiaries. The workaround collapsed. The result is a policy that simultaneously demands non-Chinese graphite (via FEOC rules) while operating in a market where non-Chinese processed graphite barely exists at commercial scale.
What the U.S. is doing about it
The CHIPS Act critical minerals pivot and the Defense Production Act investments are part of the response, but graphite-specific capacity is further behind than rare earths or lithium. The National Defense Stockpile issued requests for information on graphite in 2025, acknowledging that the U.S. has known deposits but essentially zero commercial production capacity for battery-grade material. Syrah Resources operates a graphite mine in Mozambique and a processing facility in Vidalia, Louisiana — one of the only non-Chinese anode material plants in the Western world — with Department of Energy loan support. Nouveau Monde Graphite in Quebec is developing an integrated mine-to-anode operation. Westwater Resources broke ground on a processing plant in Alabama. But these projects collectively represent a fraction of global demand, and each faces the same timeline problem that haunts every domestic critical minerals play: permitting, construction, commissioning, and ramp-up take years, and China’s export controls take effect immediately.
The friend-shoring strategy fills part of the gap. Turkey holds 27 percent of global natural graphite reserves. Brazil holds 22 percent. India, Canada, and Mexico are all potential alternative sources for raw material. But the processing bottleneck — converting raw graphite into battery-grade spherical graphite — is the constraint that raw material diversification doesn’t solve. Building a graphite processing facility takes three to five years. China built its processing dominance over three decades.
The honest picture
Graphite is the most supply-concentrated critical battery material, more concentrated than lithium, more concentrated than cobalt, more concentrated than nickel. It is in every lithium-ion battery ever manufactured. China controls the mining, the processing, the equipment, the technology, and — since October 2025 — the legal right to restrict all of it. The temporary suspension of enhanced export controls to the United States expires in November 2026. What happens after that depends on the state of U.S.-China trade relations, which at this point is like forecasting the weather on a planet with no atmosphere — the models exist but the inputs are chaos.
The copper shortage, the helium crisis, the semiconductor supply chain — each teaches the same structural lesson: the materials that modern technology depends on are sourced from fewer places, processed through fewer facilities, and controlled by fewer governments than most people realize. Graphite is the purest expression of that lesson because it’s in everything and nobody talks about it. We cover the full critical minerals landscape — from neodymium magnets to gallium export controls to graphite supply chain concentration — across our Rare Earth Elements course, where the question isn’t whether the supply chain has a single point of failure but how many single points of failure it has simultaneously.
