When the world talks about the electric vehicle revolution, the conversation usually starts with Tesla, or perhaps with BYD and CATL. But strip away the batteries and the cars, and you arrive at something more fundamental: lithium. And when it comes to lithium — the white metal at the core of virtually every rechargeable battery on earth — China’s position is structurally dominant in ways that will shape global manufacturing and trade for the next three decades.
Understanding China’s lithium supply chain is not optional for anyone in global sourcing, automotive supply, energy storage, or consumer electronics. It is essential.
The Scale of China’s Lithium Dominance
China does not produce the most raw lithium — that distinction belongs to Australia and Chile, which together account for roughly 70 percent of global hard-rock and brine extraction. But raw production is only part of the story. China processes approximately 58 to 65 percent of the world’s lithium into battery-grade lithium carbonate and lithium hydroxide, the refined forms that manufacturers actually need. No other country comes close.
The mechanism is straightforward: lithium ore mined in Australia’s Pilbara region or Chile’s Atacama Desert is shipped to Chinese processing facilities in Sichuan, Jiangxi, and Qinghai provinces, where it is refined by companies like Ganfeng Lithium (赣锋锂业), Tianqi Lithium (天齐锂业), and CITIC Guoan before being sold to battery manufacturers.
Ganfeng Lithium, founded in Xinyu, Jiangxi in 2000, is today the world’s third-largest lithium producer by output and holds equity stakes in lithium projects across Argentina, Australia, Mexico, and the Democratic Republic of Congo. Its 2023 revenue exceeded 30 billion RMB (approximately $4.2 billion USD). Tianqi Lithium, headquartered in Chengdu, owns a 26.1 percent stake in Chile’s SQM — one of the world’s largest lithium producers — giving Chinese entities indirect influence over extraction in the world’s most lithium-rich brine basin.
Domestic Reserves and Processing Capacity
China also holds significant domestic reserves. The Qinghai-Tibet Plateau contains some of the largest salt lake lithium deposits in the world, particularly at the Chaerhan Salt Lake in Qinghai Province. Exploitation of these brine deposits historically lagged due to high magnesium-to-lithium ratios, but Chinese companies have invested heavily in purification technology. By 2025, domestic Chinese lithium production capacity had more than doubled compared to 2020 levels.
Sichuan Province is the other major domestic source, hosting hard-rock spodumene deposits in the Aba and Ganzi prefectures. Taken together, China’s domestic production, combined with its overseas investment and processing dominance, creates a vertically integrated position that no other country has replicated.
From Lithium to Battery Pack: The Full Chain
Chinese dominance in lithium processing feeds directly into an equally concentrated battery manufacturing ecosystem. CATL, founded in 2011 in Ningde, Fujian, held approximately 36 percent of global EV battery market share in 2024. BYD, which manufactures its own Blade Battery cells, is the second-largest. The top five global battery manufacturers are all Chinese: CATL, BYD, CALB (中创新航), Gotion High-tech (国轩高科), and EVE Energy (亿纬锂能).
This concentration reflects two decades of deliberate industrial policy: subsidies coordinated through the Ministry of Industry and Information Technology (MIIT), a domestic EV subsidy program that ran from 2010 to 2022 and totaled hundreds of billions of RMB, and New Energy Vehicle mandates requiring automakers in China to meet production quotas. The result is a manufacturing cost advantage that Western competitors have found almost impossible to close on a like-for-like basis.
Western Policy Responses and Their Limits
The concentration of lithium processing in China has attracted significant policy attention in Washington and Brussels. The U.S. Inflation Reduction Act of 2022 contains provisions specifically designed to reduce dependence on Chinese-processed battery materials. Under the Act’s foreign entity of concern (FEOC) rules, EV tax credits are denied to vehicles whose batteries contain materials processed by Chinese companies above threshold equity levels — rules that took effect for critical minerals in 2025.
The U.S. Department of Energy’s Loan Programs Office has committed over $40 billion to domestic battery manufacturing and critical minerals processing since 2022, including loans to Albemarle, Piedmont Lithium, and multiple battery gigafactories. But building processing capacity takes time. Albemarle’s Kings Mountain lithium mine in North Carolina will not reach full production until 2028 at the earliest. Chile’s lithium nationalization policy, announced in 2023, has further complicated timelines for Western companies hoping to develop integrated supply chains outside China.
Chinese Companies Adapting to Decoupling Pressure
The Chinese response to FEOC pressure has been to accelerate overseas processing. Ganfeng Lithium’s Argentine operations — centered on the Mariana and Cauchari-Olaroz brine projects — are designed to produce lithium carbonate in-country. This model both satisfies Argentine content requirements and potentially positions the output outside FEOC thresholds, depending on equity structure.
CATL has pursued a similar strategy in Europe, with its gigafactory in Debrecen, Hungary beginning production in 2025. Manufacturing cells in the EU with European-processed materials allows CATL to serve automakers like BMW and Volkswagen without triggering FEOC-related barriers. This is a sophisticated industrial policy response — and it reflects the adaptability that has characterized China’s battery sector throughout its development.
What This Means for Foreign Businesses
Lithium supply chain dominance is one piece of a larger pattern. As covered in our analysis of China’s rare earth dominance, the country has repeatedly converted raw material advantages into vertically integrated manufacturing positions that latecomers struggle to displace. The combination of state-backed financing, a cost-competitive engineering workforce, and decades of accumulated process knowledge creates compounding advantages.
For procurement teams sourcing lithium-ion batteries — whether for EVs, power tools, grid storage, or consumer electronics — the practical implications are immediate. Chinese-processed cells that trigger FEOC rules carry a tariff premium when sold into the U.S. market, while non-FEOC cells command a scarcity premium because supply is thin. The global ambitions of Chinese automakers are inseparable from this upstream cost advantage. When analysts compare Chinese EVs to Tesla on a per-vehicle basis, the battery cost differential is one of the most significant line items.
Several strategic considerations are material for foreign companies across the electrification supply chain. Diversification is urgent: FEOC rules are already affecting vehicle eligibility and sourcing decisions at major OEMs. If your supply chain runs through Chinese-processed materials and you sell into the U.S. market, you need a clear timeline to alternatives. At the same time, Chinese lithium companies remain the most technically capable and cost-competitive partners for non-U.S. market applications — a nuance that procurement strategies must account for rather than ignore.
Monitor MIIT’s battery standards closely. Technical standards set in Beijing frequently become global defaults simply because of China’s market scale. Foreign companies not engaged in this process will find themselves adapting to Chinese decisions rather than shaping them.
The lithium supply chain is the defining industrial policy battleground of the 2020s. China built its position through consistent investment, policy alignment, and willingness to operate at industrial scales no other country has matched. The question for companies on both sides of the Pacific is not whether this dominance exists — it does — but how to build competitive, resilient businesses within a reality that will persist for the foreseeable future.
