Global Distribution of Lithium-Ion Battery Raw Material Reserves and Production
The distribution of global lithium-ion battery raw materials (lithium, cobalt, nickel, graphite, rare earths, etc.) is characterized by "highly concentrated resource reserves, significant regional monopolies in extraction/production, and a dominance of smelting and processing by China." The following is a detailed breakdown based on the latest data from the USGS and industry sources (as of 2025–2026):
I. Lithium (Li) – Core Cathode Material
Global lithium resources are primarily concentrated in the "Lithium Triangle" (Chile, Argentina, Bolivia) and Australia, though current production is dominated by Australia and Chile.
Reserves Distribution (Top 5):
Chile: ~9.2–9.3 million tonnes (approx. 25–33%), mainly brine deposits.
Australia: ~8.4 million tonnes (approx. 22–23%), mainly hard rock spodumene.
China: ~4.6 million tonnes (approx. 10–16%), a mix of brine and hard rock.
Argentina: ~4.4 million tonnes (approx. 13–15%).
United States: ~4.4 million tonnes.
Production/Mining Distribution (2024–2025):
Australia: ~88–92 thousand tonnes (approx. 37%), the world's largest producer of hard rock lithium.
Chile: ~49–56 thousand tonnes (approx. 20%), the world's largest producer of brine lithium.
China: ~41–62 thousand tonnes (approx. 17%).
Zimbabwe: ~22–28 thousand tonnes (approx. 9–10%, an emerging African supplier).
Argentina: ~18–23 thousand tonnes.
Characteristics: "Hard rock from Australia, brine from South America." While South America holds the bulk of reserves, Australia currently leads in mining capacity.
II. Cobalt (Co) – Key Material for NCM Batteries
Cobalt has the highest geographic concentration among all battery metals, with extreme dependence on a single country.
Reserves Distribution:
DR Congo: ~6.0 million tonnes (over 50–57%), the absolute global leader.
Australia: ~1.7 million tonnes (approx. 16%).
Others: Indonesia, Cuba, Philippines, etc., hold smaller shares.
Production/Mining Distribution:
DR Congo: ~170–203 thousand tonnes (approx. 70–76%).
Indonesia: ~32 thousand tonnes (approx. 12–15%, surging due to by-product cobalt from lateritic nickel mining).
Others: Russia, Australia, Canada, etc.
Characteristics: "DR Congo dominates both reserves and mining." A significant portion of Congolese cobalt is mined by Chinese-invested enterprises and exported for refining.
III. Nickel (Ni) – High Energy Density Material
Nickel resources are relatively more dispersed, but mining is highly concentrated in Southeast Asia.
Reserves Distribution:
Indonesia: ~55 million tonnes (approx. 42%), the largest globally.
Australia: ~24 million tonnes (approx. 18.5%).
Brazil: ~16 million tonnes (approx. 12.3%).
Others: Russia, New Caledonia, Philippines, etc.
Production/Mining Distribution:
Indonesia: ~1.8 million tonnes (approx. 50%), leveraging HPAL (High-Pressure Acid Leach) technology to process laterite ore for batteries.
Philippines: A traditional major miner (approx. 10–15%).
Others: Russia, New Caledonia, Australia, etc.
Characteristics: Indonesia has forced local smelting through export bans and is now the largest global supplier of battery-grade nickel (MHP/Matte).
IV. Graphite (C) – Core Anode Material
Graphite represents the segment where China's dominance is most complete.
Reserves Distribution:
China: ~78–100 million tonnes (approx. 27–35%).
Brazil: ~74 million tonnes (approx. 26%).
Others: Madagascar, Tanzania, Turkey, Mozambique, etc.
Production/Mining Distribution:
China: ~1.23–1.28 million tonnes (approx. 65–77%), ranking first globally for years.
Madagascar: ~100k tonnes (approx. 6%).
Mozambique: ~96k tonnes (approx. 6%).
Brazil: ~73k tonnes.
Characteristics: China dominates not just reserves but also mining and deep processing (high-purity, spherical graphite). China implemented export controls on certain graphite items in late 2023.
V. Manganese (Mn) & Rare Earth Elements (REE) – Auxiliary Materials & Magnets
Manganese (Mn):
Reserves: South Africa holds approx. 33% (1/3), followed by Australia, Gabon, Brazil, and China.
Production: Led by South Africa, Gabon, and Australia. Primarily used in steel; high-purity manganese for batteries relies on sophisticated refining.
Rare Earths (REE) (used in motor magnets):
Reserves: China holds approx. 38–40%, followed by Vietnam, Brazil, and Russia.
Production: China accounts for approx. 60–70%, dominating global separation and refining.

Core Conclusions:
Mismatch between Resources and Processing: Resources are located primarily in Latin America, Africa, and Indonesia, while smelting and processing capacity is concentrated in China (controlling ~65% of lithium, 74% of cobalt, 90% of rare earths, and 100% of spherical graphite processing globally).
Supply Chain Vulnerabilities: Cobalt (political stability in DRC), Nickel (Indonesian export policies), and Lithium (nationalization trends in LatAm) represent the three critical variables for future supply chain security.
Emerging Variables: Zimbabwe (Lithium), Indonesia (Nickel/Cobalt), and Brazil (Lithium) are emerging as new centers of mining growth, potentially shifting the traditional landscape.
