EV Battery Supply Chain Geopolitics — Manufacturing, Raw Materials, and the Global Power Struggle

The Battery as Geopolitical Battleground

The lithium-ion battery has become the defining industrial product of the early twenty-first century, and the supply chain that produces it has emerged as one of the most strategically contested arenas in global geopolitics. The battery sits at the nexus of the energy transition, automotive manufacturing, consumer electronics, and military technology. Whoever controls the battery supply chain, from the mines that produce its raw materials to the factories that assemble finished cells, holds decisive leverage over multiple trillion-dollar industries and the strategic capabilities of nations.

The geopolitics of the battery supply chain cannot be understood by examining any single stage in isolation. The chain comprises four critical stages: mineral extraction, mineral processing and refining, battery component manufacturing (cathodes, anodes, electrolytes, separators), and cell assembly. At each stage, the competitive dynamics, geographic concentration, and policy frameworks differ, and the strategic implications of dominance or dependency vary accordingly. What unites the entire chain is a single structural reality: China has achieved dominant or near-dominant positions at every stage, creating a level of supply chain concentration that the United States, Europe, Japan, and South Korea view as an existential strategic vulnerability.

For the Lobito Corridor and African mining more broadly, the battery supply chain represents both the primary source of demand growth for the continent's mineral endowment and the framework within which African minerals must compete for market access. Understanding the geopolitics of the battery supply chain is essential for any investor, policymaker, or mining executive seeking to position African mineral production within the global economy.

Manufacturing Concentration and Chinese Dominance

China's dominance of the battery supply chain is comprehensive and, in several segments, overwhelming. Chinese companies account for approximately 77% of global lithium-ion battery cell manufacturing capacity. Contemporary Amperex Technology Co., Limited (CATL), headquartered in Ningde, Fujian province, is the world's largest battery manufacturer by a significant margin, supplying cells to virtually every major automaker globally. BYD, which is both a battery manufacturer and the world's largest EV maker, controls the second-largest share. Together with other Chinese manufacturers including CALB, EVE Energy, Gotion High-Tech, and Sunwoda, Chinese companies produce the vast majority of the world's EV batteries.

This manufacturing dominance rests on upstream control. Chinese companies control approximately 70% of global lithium refining capacity, more than 80% of cobalt refining capacity, roughly 65% of nickel sulfate production for batteries, and more than 90% of graphite processing for battery anodes. These processing positions are fed by a combination of Chinese domestic mineral production, imports from Chinese-owned mines in Africa, Australia, South America, and Southeast Asia, and purchases from third-party miners worldwide. The integration of mining, processing, component manufacturing, and cell assembly within Chinese corporate structures and geographic clusters creates formidable cost advantages and supply chain resilience.

The South Korean and Japanese battery industries, anchored by Samsung SDI, LG Energy Solution, SK On, and Panasonic, represent the primary non-Chinese centres of battery manufacturing expertise. These companies have invested heavily in overseas manufacturing, including major facilities in the United States and Europe, and maintain technology leadership in certain battery chemistries and cell formats. However, their combined global market share has been declining relative to Chinese competitors, and they remain dependent on Chinese supply chains for significant portions of their raw material and component inputs.

The European and American battery industries are growing rapidly from much smaller bases. Gigafactory construction in both regions has been supported by massive public subsidies, including the Inflation Reduction Act in the United States and the European Battery Alliance in the EU. However, these new manufacturing facilities face a fundamental challenge: they are being built in regions that lack the integrated upstream supply chains, mineral processing capacity, and component manufacturing ecosystems that underpin Chinese battery production cost advantages.

The Global Gigafactory Race

The global race to build battery manufacturing capacity, commonly described as the gigafactory race, is one of the largest industrial investment programmes in history. Announced and under-construction battery cell manufacturing capacity globally exceeds 10 terawatt-hours (TWh) by 2030 estimates, representing hundreds of billions of dollars in capital investment. The geographic distribution of this capacity will determine the structure of the global automotive industry and the demand patterns for battery minerals for decades to come.

In the United States, the IRA has catalysed a wave of gigafactory investment. Companies including LG Energy Solution, Samsung SDI, SK On, Panasonic, and several domestic startups have announced or begun construction of major battery manufacturing facilities across the American South and Midwest. These plants are designed to serve the North American EV market and to qualify for IRA production tax credits. The total announced investment in US battery manufacturing exceeds $100 billion, though a portion of announced projects face delays, scaling challenges, or uncertain economics.

Europe has pursued a parallel strategy through the European Battery Alliance, the EU's Important Projects of Common European Interest (IPCEI) programme, and national-level subsidies. European gigafactory projects include facilities by Northvolt (Sweden), ACC (France/Germany/Italy), and investments by Asian manufacturers including Samsung SDI, LG, SK, and CATL. The EU's ambition is to produce 90% of the batteries needed for its EV market domestically by 2030, reducing dependence on imports from Asia.

China's existing and planned capacity dwarfs all other regions combined. Chinese battery manufacturers are simultaneously expanding domestic capacity and building facilities overseas, including CATL's plant in Germany and planned facilities in Hungary, as well as investments in Southeast Asia, Morocco, and other locations. Chinese manufacturers' willingness to invest globally, combined with their cost advantages and technology leadership, creates competitive pressure on Western gigafactory projects that must compete for automotive customers who prioritise price and performance.

The gigafactory race has direct implications for mineral demand. Each GWh of lithium-ion battery capacity requires approximately 800-1,200 tonnes of cathode material, depending on chemistry, which in turn requires specific quantities of lithium, cobalt, nickel, and manganese. A single large gigafactory producing 50 GWh per year may consume over 10,000 tonnes of lithium carbonate equivalent, 5,000-15,000 tonnes of cobalt (for cobalt-containing chemistries), and tens of thousands of tonnes of nickel and manganese. The aggregate mineral demand from the global gigafactory buildout is enormous and represents the primary growth driver for the mining sector over the coming decade.

Raw Material Security and Supply Risk

The raw material inputs to the battery supply chain span multiple mineral commodities, each with distinct supply risk profiles, geographic concentration patterns, and geopolitical dynamics. Understanding these commodity-specific risk profiles is essential for assessing the overall vulnerability of the battery supply chain and the strategic opportunities for African mineral producers.

Cobalt presents the most concentrated supply risk among battery minerals. The DRC produces approximately 75% of global mined cobalt, and Chinese companies control a significant share of DRC cobalt production and a commanding majority of global cobalt refining capacity. The battery industry has responded to cobalt supply risk by shifting toward lower-cobalt and cobalt-free battery chemistries, particularly lithium iron phosphate (LFP), which contains no cobalt or nickel. However, high-energy-density applications, including long-range passenger EVs and aviation, continue to require nickel-manganese-cobalt (NMC) or nickel-cobalt-aluminium (NCA) cathodes that depend on cobalt supply.

Lithium supply is more geographically diversified than cobalt, with major production in Australia (hard rock spodumene), Chile and Argentina (brine), and growing production in China, Brazil, and other countries. However, lithium processing is heavily concentrated in China, and the rapid growth of lithium demand for batteries has created periods of acute supply tightness and extreme price volatility. African lithium production, primarily from Zimbabwe, is growing but remains a small share of global supply.

Nickel for batteries requires processing into high-purity nickel sulfate, a specialised product that is distinct from the nickel pig iron and ferronickel used in stainless steel production. Indonesia has emerged as the dominant source of nickel supply growth, driven by massive Chinese-financed processing complexes that convert laterite ore into battery-grade nickel products. The environmental and social impacts of Indonesian nickel processing, particularly deforestation and tailings disposal, have raised ESG concerns that may create market segmentation between responsibly sourced nickel and Indonesian laterite-derived nickel.

Graphite for battery anodes represents perhaps the most overlooked supply chain vulnerability. China controls more than 90% of both natural graphite processing and synthetic graphite production for batteries. Natural graphite, which is mined in Mozambique, Tanzania, Madagascar, and other African countries in addition to China, requires purification to 99.95% or higher purity for battery applications, a process almost entirely conducted in China. The IRA's FEOC rules on graphite create an acute supply chain challenge given this extreme concentration.

Copper is not a cathode material but is essential to the battery supply chain as a current collector in battery cells and a primary material in EV motors, wiring, and charging infrastructure. Each EV contains 2-4 times more copper than a comparable internal combustion vehicle. The growth of the EV fleet is therefore a significant driver of copper demand, reinforcing the strategic importance of the copper-rich deposits of the DRC and Zambia that the Lobito Corridor is designed to serve.

The Mineral Processing Bottleneck

The mineral processing stage represents the most critical bottleneck in efforts to diversify the battery supply chain away from Chinese dominance. While extraction of most battery minerals is geographically distributed, China's control of processing and refining creates a chokepoint through which the vast majority of battery minerals must pass, regardless of where they are mined.

Chinese dominance of mineral processing was not accidental. It resulted from decades of deliberate industrial policy, including subsidised energy costs for processing plants, relaxed environmental standards that reduced operating costs, state-directed investment in processing technology and capacity, and a strategy of importing raw materials from global sources for domestic value addition. While Western countries exported raw ores and concentrates to the lowest-cost processor, China systematically captured the processing stage of the mineral value chain.

Breaking this processing bottleneck is the single most important challenge for battery supply chain diversification. New processing capacity requires significant capital investment, specialised technical expertise, reliable energy supply, environmental management systems, and years of construction and commissioning time. The United States, EU, and allied countries have announced substantial investments in domestic mineral processing, but the gap between announcements and operational capacity remains enormous.

For African mining, the processing bottleneck creates both a challenge and an opportunity. The challenge is that African minerals shipped to Chinese processors become entangled in FEOC supply chains, reducing their value to automakers seeking IRA compliance. The opportunity is that new non-Chinese processing capacity, particularly in Europe and North America, creates demand for African mineral feedstock that is explicitly non-Chinese in origin. Companies that can offer traceable, non-FEOC African minerals to Western processors are positioned to capture premium value in a supply-constrained market.

Trade Policy and Market Access

Trade policy has become a primary instrument of battery supply chain geopolitics. Tariffs, local content requirements, subsidy conditions, and trade restrictions are being deployed by major economies to shape the geography of battery manufacturing and mineral processing in ways that serve their strategic interests.

The United States, through the IRA, has used tax credit conditionality to redirect battery investment toward North America and FTA partners while excluding Chinese supply chains. The EU has responded with its own set of policies, including the Critical Raw Materials Act, the proposed Battery Regulation with sustainability and due diligence requirements, and targeted trade measures including anti-subsidy investigations into Chinese EV imports. The EU's approach combines market access incentives with regulatory standards that advantage European and allied producers.

China has not been passive. Beijing has imposed export restrictions on graphite and certain rare earth processing technologies, signalling its willingness to weaponise its processing dominance in response to Western supply chain diversification efforts. These restrictions create short-term supply disruptions and demonstrate that China retains significant leverage over the battery supply chain even as Western countries invest in alternatives. The graphite export restrictions are particularly consequential given China's near-total dominance of battery-grade graphite processing.

For African mineral producers, the proliferating trade policy landscape creates a complex market access environment. Minerals destined for the US market must navigate IRA requirements. Minerals destined for the EU must comply with the Battery Regulation's sustainability and due diligence provisions. Markets in China, Japan, and South Korea have their own regulatory frameworks. Companies operating in African mining must develop trade policy expertise and supply chain flexibility to serve multiple markets with different compliance requirements.

Africa's Role in the Battery Supply Chain

Africa's role in the battery supply chain is currently concentrated at the extraction stage, with minimal participation in processing, component manufacturing, or cell assembly. This positioning captures the lowest share of value addition in the supply chain while bearing the highest environmental and social costs. Changing this dynamic is a central objective of African mineral policy and of the international frameworks, including the Lobito Corridor, that seek to promote African mineral development.

The extraction stage, while low-value-add relative to downstream activities, is strategically critical. The DRC's cobalt, the DRC and Zambia's copper, Mozambique and Tanzania's graphite, Zimbabwe's lithium, and expanding exploration across the continent provide mineral feedstock that is essential to the battery supply chain. As FEOC rules and supply chain diversification imperatives reduce the attractiveness of Chinese-controlled mineral sources, non-FEOC African minerals gain strategic value.

Efforts to move African participation up the value chain, into mineral processing and ultimately into component and cell manufacturing, face enormous challenges. Reliable electricity, which is essential for energy-intensive mineral processing, is scarce and expensive in most of the DRC and parts of Zambia. Transport infrastructure, while improving through the Lobito Corridor and other investments, adds significant cost to mineral logistics. Technical capacity for advanced manufacturing processes is limited. Capital costs for processing plants are high, and financing is challenging in jurisdictions perceived as politically risky.

Despite these challenges, several in-country processing initiatives are advancing. The DRC government has pushed for in-country cobalt processing through regulatory requirements and fiscal incentives. Zambia has attracted investment in copper smelting and refining capacity. These initiatives, if successful, would significantly increase the value captured by African economies and position African producers to supply processed materials directly to Western battery manufacturers, bypassing the Chinese processing stage entirely.

Strategic Outlook

The battery supply chain geopolitical landscape will continue to evolve rapidly as the EV transition accelerates and the major economic powers compete for supply chain position. Several trends are sufficiently clear to inform strategic planning.

Chinese dominance of the battery supply chain will persist for at least the next decade, even as Western and allied countries invest aggressively in alternatives. The scale of China's existing capacity, its cost advantages, its technological capabilities, and its control of upstream mineral supply create structural advantages that cannot be offset quickly. Western battery industries will grow significantly in absolute terms but will continue to operate in a market where Chinese companies set the competitive benchmark on cost and, increasingly, on technology.

The bifurcation of the battery supply chain into Chinese and non-Chinese segments will deepen. IRA FEOC rules, EU sustainability requirements, and geopolitical risk management are creating parallel supply chains that serve different markets. Non-Chinese mineral sources, including African mines operated by Western companies, will serve the IRA-compliant and EU-compliant supply chain, while Chinese-controlled minerals will serve the Chinese domestic market and markets without FEOC-type restrictions. This bifurcation creates opportunities for non-FEOC African producers but also reduces the liquidity and efficiency of mineral markets overall.

Battery chemistry evolution will continue to shift mineral demand patterns. The rise of LFP chemistry, which uses no cobalt or nickel, reduces demand growth for these minerals relative to earlier forecasts. However, high-performance applications will continue to require cobalt-containing chemistries, and absolute demand for cobalt is projected to grow even as the cobalt intensity per kWh declines. Sodium-ion batteries, solid-state batteries, and other emerging technologies could further alter mineral demand profiles, though these technologies remain years from large-scale commercial deployment.

For the Lobito Corridor and African mining, the battery supply chain geopolitics create a clear strategic imperative: develop non-FEOC mineral production capacity, invest in logistics infrastructure that connects African mines to Western processing and manufacturing centres, and build the traceability and compliance systems that enable African minerals to serve the IRA-compliant and EU-compliant supply chain. The companies, investors, and governments that execute on this imperative will capture significant value from the battery supply chain's structural reshaping.
