Graphite processing is emerging as a critical weakness in Europe’s battery supply chain, despite receiving less attention than lithium, nickel and cobalt. Every lithium-ion battery needs an anode, and natural graphite must pass through several stages before it is suitable for battery manufacturing. Mining alone is not sufficient: purification, shaping and coating are essential to produce battery-grade material.
Much of this processing capacity is located in China, exposing European battery manufacturers to supply disruptions and market volatility. Imported graphite is not directly subject to a carbon charge under the current EU Carbon Border Adjustment Mechanism (CBAM). This limits the extent to which carbon-border policy can support lower-emission processing in Europe.
EU graphite imports remain concentrated
Eurostat recorded approximately 67,200 tonnes of EU natural-graphite imports in 2025, substantially below the peak in 2023. China represented around 43% of import value, followed by Madagascar with 18% and Brazil with 13%.
This concentration poses a strategic challenge as Europe seeks to expand electric vehicle production and strengthen domestic battery manufacturing. Export controls and market fluctuations have highlighted the risks of relying on a limited number of suppliers and processing centres. Diversifying mining sources can improve access to raw materials, but it does not by itself remove supply-chain vulnerabilities.
If battery-grade graphite continues to be processed predominantly outside Europe, manufacturers may remain reliant on external facilities even when alternative sources of natural graphite become available. As a result, diversifying where graphite is mined does not necessarily secure the processing stage needed by battery producers.
Battery-grade conversion requires specialised processing
Natural graphite needs specialised treatment to meet battery manufacturers’ performance requirements. Spheronisation, purification and coating help produce material suitable for lithium-ion battery anodes. These steps are central to converting mined graphite into a usable battery material.
The processes can require substantial quantities of electricity and chemicals, making energy costs and environmental performance important to production economics. A European processor using cleaner electricity may have a lower carbon footprint than a competing producer, but that advantage is not automatically reflected in a CBAM charge on imported graphite.
Synthetic graphite is an alternative anode material, but it is produced through a different industrial route and also requires energy-intensive, high-temperature processing. European developers must assess the relative costs, performance characteristics and environmental impacts of natural and synthetic graphite. The challenge extends beyond increasing extraction to establishing competitive facilities that can produce qualified battery materials at the quality and scale manufacturers require.
Contracts and low-carbon power affect project viability
European graphite projects need more than access to deposits or mining licences to be commercially viable. They also depend on reliable feedstock, processing technology, customer qualification and long-term sales agreements. Long-term anode offtake contracts and competitively priced low-carbon electricity can be particularly important to financing new processing capacity.
Battery manufacturers must qualify materials for their production processes, making consistent products and dependable supply central to commercial relationships. Those funding graphite projects also need to account for competition from established international processors and the availability of alternative graphite products. Projects must show that their operating models can remain competitive beyond periods of favourable market prices or temporary supply disruptions.
CRMA recognition does not guarantee customer demand
The EU Critical Raw Materials Act (CRMA) can raise the strategic importance of graphite projects and support improvements in permitting conditions. Regulatory recognition alone, however, cannot ensure that European processing facilities will secure enough customers or generate sustainable returns. Public procurement, strategic financing and recycling policies could help create demand and strengthen domestic supply chains.
In the near term, those measures may be more directly relevant to investment decisions than carbon-border policy, given graphite’s current treatment under CBAM. A key question is whether European battery manufacturers are prepared to support domestic suppliers through long-term contracts or other commercial arrangements that recognise supply security, traceability and lower emissions.
Graphite reflects a broader shift in Europe’s critical raw materials strategy: securing mineral resources is only the first stage in building a resilient industrial supply chain. Materials must also be processed into products that manufacturers can use reliably and competitively. A mine can diversify geological supply, but domestic purification and shaping capacity determine whether that diversification strengthens Europe’s battery industry.
Reducing Europe’s dependence on graphite will require coordinated investment in mining, processing, clean energy and customer relationships. Without competitive capacity to convert graphite into battery-grade material, the region risks remaining dependent on external suppliers even as it expands access to raw materials.
