Chinese Lithium Processing Dominance: Controlling 65% of Global Refining Capacity
China controls approximately 65% of global lithium refining capacity despite holding only 8% of raw reserves, having built dominant processing infrastructure that converts Australian, Chilean, and African lithium into battery-grade materials.

Processing dominance versus resource ownership#
China holds only approximately 8% of global lithium reserves but controls roughly 65% of lithium refining and processing capacity, concentrating the critical conversion step from raw spodumene or brine into battery-grade lithium carbonate and lithium hydroxide. This processing bottleneck is more strategically significant than mining, as battery manufacturers require refined lithium meeting exacting purity specifications. Companies including Ganfeng Lithium, Tianqi Lithium, and CNGR Advanced Material dominate global processing volumes. The strategy of securing processing rather than resources mirrors China approach to rare earth elements.
Upstream resource investments#
Chinese companies have secured significant upstream positions through investments in Australian lithium mines, Argentine and Chilean brine operations, and African spodumene deposits. Tianqi Lithium holds a 26% stake in SQM, one of the world largest lithium producers, while Ganfeng has offtake agreements covering multiple Australian mines. Chinese investments in Zimbabwean and DRC lithium projects are expanding rapidly. These upstream investments ensure Chinese refiners have reliable feedstock even during price volatility, while contracts channel raw material to Chinese processing facilities.
Impact on EV battery supply chains#
Every major EV battery manufacturer outside China is dependent on Chinese-refined lithium for a significant portion of their cathode material supply. Even when battery cell manufacturing occurs in the US, Europe, or Korea, the upstream lithium processing remains predominantly Chinese. This creates a structural vulnerability that IRA domestic sourcing requirements and EU battery regulation are attempting to address, but alternative refining capacity remains years from commercial scale. The lithium processing chokepoint means trade disruptions could cascade through the entire EV supply chain within months.

Diversification efforts and alternative processing#
Australia SYA Resources and Albemarle in the US are building domestic lithium hydroxide plants to reduce Chinese processing dependency, with combined capacity of approximately 100,000 tonnes annually expected by 2028. Chile is considering mandating domestic processing of a portion of its lithium output. The EU Critical Raw Materials Act includes targets for domestic processing of 40% of European lithium consumption by 2030. These diversification efforts face significant challenges including higher energy costs and the technical expertise gap compared to Chinese operators.
Price influence and market dynamics#
Chinese processors dominant market position gives them significant influence over global lithium pricing, with inventory management decisions by major Chinese refiners visibly affecting spot market prices. During the lithium price collapse of 2023-2024, Chinese processors decisions to curtail or maintain production determined the pace and depth of price adjustment. Companies should consider long-term offtake agreements with diversified lithium sources and support the development of non-Chinese processing alternatives to reduce structural price vulnerability.
People also ask
How much of global lithium processing does China control?
China controls approximately 65% of global lithium refining capacity despite holding only 8% of raw reserves, dominating the critical conversion step from raw lithium minerals into battery-grade materials.
Why does China dominate lithium processing?
China built dominant lithium processing infrastructure through two decades of deliberate industrial policy, lower energy costs, established technical expertise, and strategic investments in upstream mining operations across Australia, South America, and Africa.
Can lithium be processed outside China?
Alternative processing capacity is being developed in Australia, the US, and Chile, but currently accounts for less than 35% of global refining. Reaching commercial scale comparable to Chinese operators is expected to take until 2028-2030.
