How the lithium triangle (Chile/Argentina/Bolivia), DRC's cobalt dominance, and China's 75% lock on battery-grade processing have turned EV battery materials into geopolitical flashpoints — with price volatility swings of 10x in three years.

Lithium and cobalt are the essential inputs for lithium-ion batteries powering EVs. Their geographic concentration and processing dominance have turned them into geopolitical flashpoints.
Lithium Triangle (Chile/Argentina/Bolivia): 60%+ of world's identified reserves. Brine-based extraction: pump mineral-rich brine to surface, evaporate in ponds for up to 18 months. Water-intensive in one of Earth's driest regions. Australia: largest producer of hard-rock spodumene (open-pit, energy-intensive processing).
DRC: ~70% of global cobalt output. Primarily mined as byproduct of copper. 10-20% from artisanal/small-scale mining (ASM) — child labor, hazardous conditions, no regulatory oversight. This creates ESG liability for Western auto OEMs. Response: battery manufacturers shifting to LFP (Lithium Iron Phosphate) chemistry that eliminates cobalt entirely.
China doesn't hold the most raw reserves, but controls ~75% of battery-grade lithium refining and ~70% of cobalt refining. Also manufactures most battery anodes, cathodes, and cells. The US IRA and EU Critical Raw Materials Act are paying billions to localize this supply chain — but permitting timelines and capital requirements make this a decade-long project.
2021: Lithium carbonate: ~$8,000/metric ton. 2022 peak: $85,000/metric ton (10x). By 2024: crashed back to $10,000-12,000 as new supply flooded in and EV demand growth slowed. Classic commodity boom-bust. See Iron Ore and Copper.
