What is graphite? It is a naturally occurring crystalline form of pure carbon — and the single most important material in the lithium-ion battery anode, making it as critical to the energy transition as lithium itself. Designated a critical mineral by the UK, US, EU, and Canada, graphite faces severe supply chain concentration risk: China controls more than 90% of the world’s processing capacity for battery-grade material.
What Is Graphite? Properties and Characteristics
Graphite is one of three naturally occurring allotropes of carbon, alongside diamond and fullerene. Where diamond is the hardest mineral known, graphite sits at the opposite extreme — soft, slippery, and electrically conductive. These properties stem from its layered hexagonal structure: carbon atoms are bonded tightly within each sheet but held between layers only by weak van der Waals forces, allowing sheets to slide freely over one another.
Key physical properties that make graphite commercially indispensable:
Electrical conductivity — graphite conducts electricity along its basal planes, making it the material of choice for electrodes and current collectors. Thermal stability — graphite withstands temperatures approaching 4,000°C in inert atmospheres, a property exploited in electric arc furnaces and nuclear reactors. Chemical inertness — it resists attack from most acids and alkalis under standard conditions. Lubricity — the layered structure enables graphite to function as a dry lubricant in high-temperature environments where oils would degrade.
Natural vs Synthetic Graphite: The Two Supply Routes
Battery manufacturers draw on two distinct forms of graphite with fundamentally different production economics.
Natural graphite is mined directly from the earth in three commercial grades: flake graphite (the primary battery feedstock), amorphous graphite (used in refractory and industrial applications), and vein graphite (a rare, high-purity form found primarily in Sri Lanka). Raw flake graphite requires chemical purification — typically with hydrofluoric acid — to reach the 99.95%+ carbon purity required for battery anodes. This purification step carries significant environmental and regulatory risk, and is performed almost exclusively in China.
Synthetic graphite is manufactured by heating petroleum coke or coal tar pitch to temperatures above 2,500°C in a process called graphitization. The result is a highly consistent, high-purity product preferred for performance-critical battery applications. Synthetic graphite commands a premium price over natural graphite, but its production is energy-intensive and tied to fossil fuel derivative feedstocks — an inherent tension for battery manufacturers targeting low-carbon supply chains. A 2026 review in Nature Reviews Materials identifies green synthesis from renewable carbon sources — including biomass-derived precursors and plasma processing — as the critical development pathway for reducing synthetic graphite’s environmental footprint.
What Is Graphite Used For?
Graphite’s combination of electrical conductivity, thermal resilience, and chemical stability makes it useful across a broad range of industries — but the battery sector now dominates demand.
| Sector | Application | Graphite Type |
|---|---|---|
| EV batteries | Lithium-ion battery anodes | Natural (spherical purified) or synthetic |
| Consumer electronics | Smartphone and laptop battery anodes | Synthetic (high consistency) |
| Steelmaking | Electric arc furnace electrodes, refractories, crucibles | Synthetic (large electrode grade) |
| Aerospace & defence | Heat shields, structural composites, brake systems | High-purity natural or synthetic |
| Nuclear energy | Neutron moderators in reactor cores | High-purity nuclear grade |
| Industrial | Lubricants, gaskets, seals | Amorphous or fine flake |
Battery applications account for an estimated 40–50% of global flake graphite demand as of 2026, a share that is rising rapidly. An electric vehicle battery requires roughly 50–100 kg of graphite for its anode — more by weight than the lithium it contains. For context on how this feeds into broader critical minerals processing infrastructure requirements, the anode manufacturing supply chain involves mining, purification, spheronisation, and coating — with China holding dominant positions at each stage.
Where Is Graphite Produced?
According to USGS Mineral Commodity Summaries, global natural graphite mine production was approximately 1.3 million tonnes in 2024. China accounted for around 800,000 tonnes — roughly 62% of mined output. Mozambique has emerged as the second-largest producer, followed by Madagascar, Brazil, and India.
Mine production figures, however, understate China’s true market position. Chinese processors control the spherical purification and coating steps that transform raw flake graphite into battery-ready anode material. Even graphite mined in Mozambique or Madagascar is typically shipped to China for processing before being sold to battery manufacturers in South Korea, Japan, or Europe. Western processing capacity outside China remains negligible as of mid-2026.
Graphite Price and Market
Graphite pricing varies significantly by grade and form. Flake graphite (+80 mesh, 94–97% carbon) traded at approximately $400–$500 per tonne in early 2026, down sharply from the peaks seen during the 2022–2023 battery metals supercycle. Spherical purified graphite (SPG), the battery anode feedstock, commands a substantial premium — typically $1,500–$2,500 per tonne depending on carbon purity and particle size specification.
The graphite market is not exchange-traded in the way that cobalt or nickel are priced on the LME. Prices are assessed by specialist agencies including Fastmarkets and Asian Metal. For current benchmark data, see the CMN graphite price tracker.
Graphite Supply Chain Risks
Graphite presents one of the most acute supply chain concentration risks in the entire critical minerals landscape — a concern reflected directly in its designation on government critical minerals lists. The risks operate at two levels.
Processing concentration: China’s dominance of battery-grade graphite processing means that any export restriction — of the kind applied to gallium and germanium in 2023, and to antimony in 2024 — could immediately disrupt anode supply globally. China implemented graphite export licensing controls in October 2023, requiring exporters to apply for permits. The full effect of those controls on Western supply chains is still working through the market. For a broader analysis of China’s approach across the critical minerals complex, see the CMN guide to China critical minerals export controls.
Processing capacity outside China: Several Western anode projects are in development — including operations in the US, Canada, and Europe — but none has reached commercial scale as of mid-2026. The gap between stated project timelines and actual production start dates has been a persistent feature of Western critical minerals investment. Recycling of spent battery anodes represents a longer-term secondary supply route, though commercial-scale graphite recycling remains nascent.

What is graphite and why is it a critical mineral?
Graphite is a naturally occurring form of pure carbon with high electrical conductivity and thermal stability. It is classified as a critical mineral because it is the primary material used in lithium-ion battery anodes and faces severe supply chain concentration risk, with China controlling more than 90% of battery-grade processing capacity.
What is graphite used for in EV batteries?
Graphite forms the anode — the negative electrode — of lithium-ion batteries. An EV battery contains 50–100 kg of graphite by weight, more than the lithium it contains. Lithium ions intercalate between graphite layers during charging and release during discharge, making graphite’s layered structure fundamental to battery operation.
What is the difference between natural and synthetic graphite?
Natural graphite is mined from the earth and purified to battery grade using chemical processes. Synthetic graphite is manufactured by heating petroleum coke or coal tar pitch above 2,500°C. Synthetic graphite offers greater consistency and purity and is preferred for high-performance battery applications, but its production is energy-intensive. Both types are used in EV battery anodes.
Which countries produce the most graphite?
China is the world’s largest graphite producer, accounting for around 62% of global mine output. Mozambique, Madagascar, Brazil, and India are significant secondary producers. However, China also dominates the processing of raw flake graphite into battery-grade spherical purified graphite, making its market position considerably stronger than mining statistics alone suggest.
What is the current graphite price?
Flake graphite (+80 mesh, 94–97% carbon) traded at approximately $400–$500 per tonne in early 2026. Spherical purified graphite — the battery anode feedstock — commands a substantial premium at $1,500–$2,500 per tonne depending on specification. For current benchmark prices, see the CMN graphite price tracker page.
Has China restricted graphite exports?
Yes. China introduced graphite export licensing controls in October 2023, requiring exporters to obtain permits for battery-grade graphite shipments. These controls followed earlier restrictions on gallium and germanium and form part of a broader Chinese government approach to leveraging critical minerals supply chain positions in response to Western technology trade restrictions.
