What Is the Lithium Triangle and Why Does It Matter?

The Lithium Triangle is a high-altitude crescent spanning Argentina, Chile, and Bolivia that holds 58 percent of the world’s identified lithium resources, making it critical infrastructure for the battery-dependent energy transition.

Argentina, Bolivia, and Chile hold about 56% of the world’s Lithium reserves overall, with Bolivia alone containing roughly 21%, the largest share globally, according to Catalyst McGill. The region’s vast salt flats trap lithium in underground brine, where evaporation under intense solar radiation concentrates the metal for extraction. The core of Salar de Atacama in Chile has the highest concentration of lithium (0.15% by weight) among all world’s brine sources.

Yet reserves alone do not determine market power. Chile accounted for 80% of global lithium carbonate exports as of 2022, Argentina is the third largest exporter at almost 7%, and Bolivia accounts for less than 1% despite having the largest reserves, according to a Lawrence Livermore National Laboratory analysis. Political decisions over extraction models now shape who benefits from the electric vehicle boom and whether the Triangle becomes a supply anchor or a bottleneck.

The Political Divergence Reshaping Supply

The three countries have adopted radically different governance models for lithium, fragmenting what could have been a coordinated bloc. Argentina has adopted a more decentralized, market-driven approach, Bolivia has established a state-controlled model, and Chile has mobilized a hybrid governance system with both public and private involvement, according to ScienceDirect research on sustainability challenges.

Argentina’s libertarian president Javier Milei has accelerated foreign investment through the Large Investment Incentive Regime (RIGI), which offers tax, customs, and exchange rate benefits for investments of more than $200 million. Argentina expects to produce 130,800 tonnes of lithium carbonate equivalent in 2025, a 75% increase from 2024, driven by new operations in Salta and expansions in Catamarca and Jujuy, the Argentine Chamber of Mining Companies told Mining.com. Rio Tinto committed $2.5 billion to build a processing plant at the Rincon mine with annual capacity of 60,000 metric tons of lithium carbonate, the first major project approved under RIGI.

Chile has moved in the opposite direction. President Gabriel Boric’s National Lithium Strategy, announced in April 2023, established a state-owned National Lithium Company with participation throughout the production cycle, initially led by copper giant Codelco, with the state retaining majority stakes in projects deemed strategic, according to UNCTAD. In 2025 the joint venture Nova Andino Litio was established between Codelco and SQM, with Codelco maintaining control of the assets while SQM runs the operation in Salar de Atacama. By 2031, Chile will receive 85 percent of the partnership’s operating margin.

Bolivia possesses 24% of the world’s total lithium reserves but has struggled to convert geological wealth into commercial output. State-run lithium company YLB produced 2,000 metric tons in 2024 with revenues of $15.6 million, less than 1% of Chile’s annual production of approximately 300,000 tons, according to Discovery Alert. High magnesium concentrations in brine deposits make traditional evaporation pond methods inefficient, requiring specialised direct lithium extraction technologies, and the magnesium-rich brines create technical complications that increase operational costs and extend development timelines.

Water, Land, and the Hidden Cost of Extraction

Lithium extraction consumes vast quantities of water in one of Earth’s driest regions, creating tensions with indigenous communities and agricultural users. About half a million gallons of water evaporate for every ton of lithium carbonate collected, according to chemist Victoria Flexer at Argentina’s CONICET, cited by Yale Environment 360.

In Chile’s Salar de Atacama, lithium and copper extraction have reportedly consumed over 65% of the local water supply, depleting available water for Indigenous farming communities in an already water-scarce region, the World Resources Institute reports. Indigenous peoples including the Lickanantay (Atacameño) have faced loss of vegetation cover and the disappearance of lagoons they depend on, driven primarily by extraction methods that involve pumping saline water to the surface and allowing it to evaporate, producing an irreversible and unrecoverable loss of large volumes of water from the aquifer.

Lithium-rich water is pumped into large evaporation ponds and left to dry under the sun and wind, causing the gradual disappearance of wetlands and depleting water that communities desperately need for agriculture and sustenance, according to a FIDH human rights study.

On the Hombre Muerto salt flat in Argentina, locals report that pumping for the 25-year-old Fenix operation has lowered the water table so much that the Trapiche River, a major source of water for their meadows, has dried up, and communities have mobilized to prevent the same happening to their other main source, the Patos River. The Argentinian government and provincial authorities provide little oversight, giving companies freedom to organize their own environmental assessments and community liaisons, and analysis of 11 company environmental impact assessments found none included full hydrological analysis or rigorous assessment of evaporation ponds’ impact on local water supplies and wetlands.

China Controls What Matters: Refining and Batteries

The Triangle’s resource endowment is undermined by a critical asymmetry: China dominates every downstream stage of the Battery Supply Chain, from refining raw lithium to manufacturing cells. China processes around 60–70% of global lithium, produces about 75% of battery cells, and controls the majority of anode and cathode output.

China processes over 90% of the world’s graphite, and in 2022 Chinese companies accounted for over two-thirds of the world’s cobalt and lithium processing capacity, according to the U.S. Energy Information Administration. China imported almost 12 million short tons of raw and processed battery minerals (44% of interregional trade) and exported almost 11 million short tons of battery materials, packs, and components (58% of interregional trade) in 2023.

Chinese firms like CATL and BYD command massive market shares—CATL alone holds roughly 38%, while BYD accounts for about 17%—and China’s firms also invest deeply into extraction, refining, and recycling operations in the Lithium Triangle via joint ventures and minority stakes. Chinese investments in lithium-rich countries like the Lithium Triangle will allow it to further vertically integrate the supply chain for lithium-ion batteries, according to Orcasia analysis.

Australia, the world’s largest lithium producer, sent almost all its exports to China alone in 2023. Even lithium mined in South America typically passes through Chinese refineries before entering battery production. China controls roughly 70–80% of global lithium-ion battery cell production, as well as over 80% of cathode, 90% of anode, and over 85% of electrolyte manufacturing, with dominance extending upstream to over 70% of global lithium refining capacity and more than 90% of graphite processing, according to a National Interest analysis.

Downstream Stakes: EVs, Grid Storage, and Cost Curves

Lithium price volatility directly affects electric vehicle affordability and energy storage deployment. Lithium prices have fallen significantly, putting the cost of cells at 5-9% of the price of an EV as of August 2024, down from 11-20% in January 2023, according to Fastmarkets.

Lithium-ion battery prices dropped 8% in 2025 to $108 per kilowatt-hour, BloombergNEF reports, with battery pack prices for stationary storage dropping to $70/kWh in 2025 (45% lower than 2024), making it the lowest-priced segment for the first time, while battery electric vehicle packs were at $99/kWh. The United States installed a record 57.6 GWh of new energy storage capacity in 2025, with lithium-ion battery cell manufacturing for stationary storage rising to over 21 GWh, enough to power Houston from sunset to sunrise.

An undersupply of lithium would push up prices, benefiting the mining sector but harming battery and EV makers as well as final consumers, with the recycling sector also benefiting from higher mineral prices, the International Energy Agency notes. However, due to feedstock limitations, it will take about a decade before recycling has a significant impact on reducing primary mineral demand.

The gap between Triangle reserves and processing capacity creates strategic vulnerabilities. If Bolivia successfully scales production and Argentina maintains investment momentum while Chile expands under state control, supply could surge. But without local refining infrastructure, the Triangle remains a raw material exporter dependent on Chinese processing—a position that limits bargaining power and value capture.
