As the global demand for electric vehicles and renewable energy solutions surges, the spotlight often shines on lithium, cobalt, and rare earth elements. However, two critical materials that are fundamental to the success of the battery economy—nickel and graphite—remain largely overlooked. These materials are not merely supplementary; they are foundational to battery performance and scalability, making their role indispensable in the electrification landscape.
Nickel’s Evolution: From Industry to Battery Essential
Projected global nickel production is set to reach approximately 3.8 to 4.2 million tonnes by 2025, reflecting a significant uptick in output compared to other battery materials. Traditionally utilized in stainless steel and industrial applications, nickel has gained prominence due to its essential function in high-performance lithium-ion batteries. Nickel-rich cathode technologies, such as NMC (nickel-manganese-cobalt) and NCA (nickel-cobalt-aluminum), are pivotal for electric vehicle batteries, offering enhanced energy density that translates into improved driving range and performance.
Indonesia stands out as a key player in the nickel market, producing over 2 million tonnes annually—more than half of the global supply when measured in ore-equivalent terms. The country has strategically shifted from being a raw material exporter to a midstream powerhouse by investing in processing capabilities and enforcing local value addition, thus reshaping the global nickel supply chain.
The Geopolitical Landscape of Nickel Supply
Beyond Indonesia, nickel production is dispersed across regions including Australia, Canada, New Caledonia, the Philippines, Russia, and parts of Africa, yielding an additional 1.8 to 2.2 million tonnes annually. Each region faces distinct challenges: Russian supplies are hampered by sanctions; Philippine operations contend with environmental concerns; while Australian and Canadian sources offer strong ESG credentials but at higher costs. African projects present potential but require significant infrastructure investment and political stability.
Europe’s nickel production is alarmingly low at less than 100,000 tonnes per year against a consumption rate of approximately 300,000 to 400,000 tonnes. This dependency on imports poses a strategic challenge for Europe as it seeks greater autonomy in critical raw materials.
Graphite: The Backbone of Battery Manufacturing
Graphite plays an equally crucial role in battery technology; every lithium-ion battery relies on graphite for its anode. Global production exceeds 1.4 million tonnes annually, yet this figure belies graphite’s critical importance—without it, battery manufacturing would cease entirely. Currently dominated by China, which controls 65-70% of global natural graphite production and processing capacity, the supply chain for graphite is heavily centralized.
Emerging suppliers from East Africa are beginning to make their mark on the graphite landscape, with several projects poised for production growth over the next few years. This development is vital as demand for graphite is expected to soar into the millions of tonnes annually by the 2030s due to increasing electrification targets.
The Interconnectedness of Nickel and Graphite
Together, nickel and graphite form the backbone of the battery economy. While lithium defines chemical properties within batteries, nickel enhances performance metrics such as range and charging speed, whereas graphite ensures the physical functionality necessary for battery existence. Major automotive manufacturers depend on a stable supply of both materials to meet consumer expectations and regulatory requirements.
The Challenges Ahead: Processing Dominance
The processing stage represents a critical leverage point for both nickel and graphite. Nickel must be converted into battery-grade products like nickel sulfate, while graphite requires purification and shaping for effective use in anodes. Currently, Asia dominates this midstream processing sector.
Despite European efforts to establish gigafactories for battery production, many plans still rely on imported processed materials. This reliance raises concerns about structural fragility akin to building power stations without securing fuel supplies.
The Future Outlook: Risks and Dependencies
The combined global output of approximately 4 million tonnes of nickel and 1.4 million tonnes of graphite appears insufficient against rapidly rising demand curves driven by electrification initiatives. As these trajectories diverge without alignment, risks escalate significantly.
Nickel ensures performance while graphite secures existence; together they underpin a battery economy currently valued in hundreds of billions of euros with projections reaching trillions by the end of the decade. Their understated yet vital roles highlight an essential truth: often the most critical resources are those that operate quietly behind the scenes—failures here could halt progress across entire industries.
