Global Lithium Supply: Which Countries Lead the World's Lithium Reserves?

The global shift toward electric vehicles and renewable energy storage has intensified focus on lithium as a critical resource. Understanding the distribution of the world's lithium reserves across different countries by lithium reserves is essential for investors and industry participants seeking to gauge future supply dynamics.

Worldwide lithium reserves totaled approximately 30 million metric tons as of 2024, according to data from the US Geological Survey, with reserves measured in terms of contained lithium content. Among all countries by lithium reserves globally, four nations stand out for their commanding positions, collectively holding the majority of economically viable deposits.

Chile: The Undisputed Leader

Chile dominates global lithium reserves with 9.3 million metric tons, representing roughly one-third of the world's lithium reserve base. The Salar de Atacama region accounts for approximately 33 percent of global lithium resources, housing most of the world's "economically extractable" deposits.

Despite these vast reserves, Chile ranked as the world's second-largest lithium producer in 2024, outputting 44,000 metric tons. This apparent paradox stems partly from Chile's stringent mining concession frameworks. Major producers SQM and Albemarle operate extensively in the Salar de Atacama, though recent government actions have shifted the landscape significantly.

In April 2023, Chilean President Gabriel Boric unveiled plans to partially nationalize the lithium industry, with state-owned Codelco negotiating for substantial stakes in both SQM and Albemarle's lithium assets. The move aimed to strengthen the economy while safeguarding environmental interests. Early 2025 brought fresh momentum, with the government receiving seven bidding proposals for lithium operation contracts across six salt flats, with winners to be announced in March 2025.

Australia: Production Powerhouse

Australia's lithium reserves of 7 million metric tons rank second globally, yet the country emerged as the world's largest lithium producer in 2024. A crucial distinction lies in deposit type: while Chile and Argentina rely on lithium brines, Australian reserves predominantly consist of hard-rock spodumene deposits concentrated in Western Australia.

The Greenbushes lithium mine, jointly operated by Talison Lithium—a partnership involving Tianqi Lithium, IGO, and Albemarle—has supplied lithium continuously since 1985 and remains among the world's most significant operations. Recent price volatility prompted several Australian lithium companies to temporarily suspend or reduce production and development activities.

Emerging research has identified substantial untapped potential beyond Western Australia's traditional mining zones. University of Sydney researchers, collaborating with Geoscience Australia, developed the first comprehensive lithium soil density map, revealing elevated concentrations in Queensland, New South Wales, and Victoria that could serve as future extraction sites.

Argentina: The Rising Producer

Argentina commands 3 to 4 million metric tons of lithium reserves, positioning it as the third among countries by lithium reserves. As a component of the Lithium Triangle alongside Chile and Bolivia, Argentina benefits from proximity to deposits harboring more than half the world's lithium reserves.

In 2024, Argentina produced 18,000 metric tons and ranked fourth globally in output. The government has signaled strong commitment to expansion: a 2022 investment pledge allocated up to US$4.2 billion toward lithium industry development over three years. The April 2024 approval of Argosy Minerals' capacity expansion at Rincon salar demonstrated continued momentum, with plans to increase production from 2,000 to 12,000 metric tons annually.

Mining giant Rio Tinto announced even more ambitious plans in late 2024, committing US$2.5 billion to boost Rincon salar capacity from 3,000 to 60,000 metric tons by 2028. Argentina currently hosts approximately 50 advanced lithium mining projects, underscoring its trajectory as a major future supplier in the countries by lithium reserves landscape.

China: Strategic Producer with Growing Reserves

China's 3 million metric tons of lithium reserves represent a smaller proportion of global deposits, yet the nation's significance extends far beyond raw reserve volumes. Chinese lithium deposits comprise a diverse mix of brines, spodumene, and lepidolite hard-rock reserves.

China produced 41,000 metric tons in 2024, yet still imports the majority of lithium required for its battery manufacturing operations. The nation's dominance in lithium-ion battery production and processing—hosting the majority of the world's facilities—makes it a central hub in the global supply chain despite comparatively modest reserves.

In October 2024, US State Department officials accused China of implementing predatory pricing strategies to suppress international competition, with Jose W. Fernandez noting, "They engage in predatory pricing… (they) lower the price until competition disappears."

Chinese media reports from early 2025 announced a significant reserve reassessment, claiming national deposits now represent 16.5 percent of global resources, up from 6 percent. The reevaluation reflects discoveries including a 2,800-kilometer lithium belt in western regions with proven reserves exceeding 6.5 million tons of lithium ore and potential resources surpassing 30 million tons. Enhanced extraction techniques from salt lakes and mica have further augmented estimated reserves.

Additional Countries in the Global Lithium Supply Chain

Beyond the four largest reserve holders, numerous nations maintain substantial lithium deposits:

• United States: 1,800,000 metric tons
• Canada: 1,200,000 metric tons
• Zimbabwe: 480,000 metric tons
• Brazil: 390,000 metric tons
• Portugal: 60,000 metric tons (Europe's largest)

Portugal produced 380 metric tons in 2024, maintaining stable output. As the lithium sector expands, an increasing number of these reserve-rich nations are transitioning into active producers.

Key Insights on Global Lithium Distribution

The Lithium Triangle—encompassing Chile, Argentina, and Bolivia—accounts for an outsized share of the world's lithium reserves, positioning South America as the epicenter of global supply. Hard-rock deposits in Australia provide geographic diversification, while emerging discoveries in additional countries signal future market transformation.

With demand for lithium-ion batteries projected to surge by over 30 percent year-on-year in 2025 for both electric vehicle and energy storage applications, the distribution of countries by lithium reserves will increasingly shape geopolitical and economic priorities in the energy transition era.
