Global lithium demand is expected to grow by 13.5% in 2026, reaching 1.48 million tonnes of lithium carbonate equivalent (LCE), but supply will not keep pace: a deficit of 80,000 tonnes is looming according to Morgan Stanley projections. This anticipated shortage is reshaping the geopolitics of critical raw materials, with Latin America at the heart of a strategic triangle that holds 60% of global reserves. But behind these promising figures lies a persistent dependence: according to S&P Global 2024, China controls 60%+ of battery-grade lithium refining, with some analyses including Chinese projects abroad speaking of 75%+ of global refining (including indirect control), transforming South America’s geological advantage into industrial subordination.

Energy storage surpasses automotive as growth driver

The usual narrative links the explosion in lithium demand to electric vehicles. The 2026 data tells a different story. Battery energy storage systems (BESS) are becoming the main growth driver, with expansion rates of 40 to 60% in China according to S&P Global Energy. This transformation is explained by the intermittency of renewable energy: each gigawatt of wind or solar installed requires storage capacity to stabilize the grid.

The gap is widening rapidly. While global electric vehicle sales are progressing by 15-20% annually, stationary storage installations are exploding. China alone is installing more than 35 GW of BESS capacity in 2025, requiring approximately 280,000 tonnes LCE. Europe and the United States are also accelerating: the American Inflation Reduction Act provides for tax credits for 30 GW of storage by 2030.

This transformation is changing the geography of demand. Automotive manufacturers negotiate stable multi-year contracts, while electrical grid operators create more volatile but massive demand. Tesla Megapack, BYD or CATL sign agreements with utilities for entire gigafactories dedicated to residential and industrial storage.

Argentina, Chile and Bolivia hold the keys to a natural oligopoly

The lithium triangle concentrates a geological anomaly. The Atacama, Uyuni and Hombre Muerto salars contain considerable reserves, with Latin America possessing about 60% of identified global reserves. Bolivia has 21 million tonnes, or about 18-25% of identified global reserves (varying according to source and year). This geographical concentration creates a natural oligopoly that three countries can leverage, unlike hydrocarbons scattered across five continents.

Extraction costs vary drastically according to geology. In Chile, SQM extracts lithium from the Atacama salar for $3,500 per tonne LCE, while hard rock extraction in Australia costs $8,000 to $12,000. Argentina is developing 40 lithium projects with average costs of $4,200 per tonne. Bolivia, despite having the world’s largest reserves (21 million tonnes), struggles to industrialize: its lithium remains trapped in complex brines with high magnesium content.

This geography shapes divergent national strategies. Chile imposes extraction quotas to preserve local ecosystems: 180,000 tonnes LCE maximum until 2030. Argentina favors attracting foreign investment with an advantageous tax regime. Bolivia attempts to develop an integrated state-controlled sector, but accumulates industrial delays.

Mining giants are adapting their portfolios. Albemarle invested $1.3 billion in building a new lithium processing plant in Chester County, South Carolina (announced in 2022), and $3.1 billion in a DLE project in Atacama, Chile according to 2026 regulatory filings. Ganfeng Lithium, the Chinese champion, already controls concessions in Argentina through its subsidiary Minera Exar. The challenge goes beyond extraction: capturing the added value of refining, monopolized by Asia.

China controls 75% of global refining despite zero domestic reserves

A striking geopolitical paradox: China processes 75% of global lithium into industrial products while importing 95% of its raw material. This refining dominance illustrates a coherent industrial strategy, built since 2010 when Beijing identified critical metals as a national priority.

Chinese refineries process 420,000 tonnes LCE annually. Ganfeng Lithium, Tianqi Lithium and Sichuan Yahua dominate an oligopolistic market. Their plants in Jiangxi and Sichuan apply standardized processes: purification by precipitation, electrolysis and controlled crystallization. Gross margins reach 40-60% on refined lithium carbonate, versus 15-25% on primary extraction.

This vertical integration locks up the value chain. BYD owns its own refineries to supply its battery gigafactories. CATL secures its supplies through partnerships with South American miners. Result: lithium triangle producers sell their raw material at $15,000 per tonne, while final batteries incorporate $45,000 worth of refined lithium per tonne.

Europe and the United States are trying to catch up with this industrial lag. Germany finances three lithium refineries through its climate plan. The United States classifies lithium as “critical material” and subsidizes domestic plants. But the technological gap remains huge: Western refineries show yields of 85%, versus 92% for latest-generation Chinese installations.

Lithium prices reveal tensions in an unbalanced chain

Lithium carbonate prices trace a roller coaster that betrays structural imbalances. After peaking at $85,000 per tonne at the end of 2022, prices fell to $12,000 mid-2024 before climbing back to $18,000 according to Benchmark Mineral Intelligence quotations.

This volatility reveals a fragmented supply chain. South American miners sign multi-year extraction contracts indexed to complex formulas. Chinese refiners stockpile massively during lows to supply their gigafactories. Automotive manufacturers panic and over-secure their supplies, amplifying the cycles.

The anticipated deficit of 80,000 tonnes in 2026 could propel prices toward $35,000-40,000 per tonne according to several analysts. But this projection assumes linear demand and constrained supply. However, dormant projects can restart if prices justify higher extraction costs. Australia has hard rock deposits exploitable from $25,000 per tonne.

The macroeconomic implications go beyond the mining sector. A lithium shortage would delay the energy transition and maintain dependence on fossil fuels. Conversely, an overabundance could trigger a destructive price war for marginal producers. Argentina, whose lithium exports represent $2.1 billion, would see its tax revenues fluctuate brutally.

Vertical integration as the only way out for Latin America

Faced with Chinese dominance in refining, can Latin America move up the value chain? Several encouraging signals are emerging. Argentina is building its first lithium refinery in Jujuy, capacity 25,000 tonnes LCE, operational in 2027. Chile is studying a public-private partnership to develop a national refining industry.

These initiatives face considerable technical and financial obstacles. A modern lithium refinery costs $400 to $600 million and requires specialized chemical expertise. Specialized engineers number in the hundreds worldwide, mainly in China and South Korea. Purity standards require 99.5% minimum for automotive batteries, versus 95-97% for conventional industrial applications.

The challenge goes beyond technology: creating integrated industrial ecosystems. Chile is betting on green hydrogen to power its future lithium refineries with decarbonized energy. Argentina is negotiating with European manufacturers to establish local gigafactories. These strategies are inspired by the Norwegian model, which transformed its oil resources into cleantech leadership.

The innovation dynamic between China and the West illustrates geopolitical tensions around critical technologies. Latin America could benefit from this competition by negotiating technology transfers with the most offering partners.

Strategic partnerships redefine lithium geopolitics

Europe and the United States are developing raw materials diplomacy to reduce their Chinese dependence. The European Union signs strategic mining agreements with Argentina and Chile as part of its “critical raw materials strategy.” Germany finances responsible extraction projects in exchange for guaranteed supply quotas.

These partnerships transcend traditional commercial relationships. Stellantis invests $155 million in Argentine mines through its Free2Move eSolutions subsidiary. BMW secures 285,000 tonnes of Chilean lithium over ten years with environmental sustainability clauses. These agreements integrate technical training, technology transfers and ESG (environmental, social and governance) standards.

The American strategy favors hemispheric integration. The “Minerals Security Partnership,” launched by Washington with eleven allies, finances mining infrastructure in Latin America. The objective: create “friend-shoring” supply chains excluding China from critical segments.

Beijing responds by strengthening its positions. China Molybdenum buys shares in Congolese and Chilean mines. Ganfeng Lithium negotiates joint-ventures with Argentine producers. This geopolitical escalation transforms lithium into an economic weapon, as oil or rare earths once were.

Optimism remains conditional. If Latin America manages to capture 30% of refining value added by 2030, lithium triangle revenues could double, reaching $12 billion annually. But this industrial upgrading requires massive investments, political stability and technical skills that only international technological partnerships can provide. The equation remains complex: transforming geological advantage into industrial leadership without reproducing the dependency errors that still characterize South American extractive economies.
