Summary
Lithium is the lightest metal on the periodic table and the foundational input for all lithium-based battery chemistries — including every technology documented in the batteries knowledge base. It is extracted primarily via two routes: hard rock spodumene mining (Australia, principally) and brine evaporation (the “Lithium Triangle” of Chile, Argentina, and Bolivia). The critical geopolitical vulnerability is not at the mining stage but at the processing stage: China dominates the conversion of raw lithium into battery-grade lithium hydroxide and lithium carbonate, creating a chokepoint even for material mined in friendly countries.
Key Facts
- Chemical formula: Li (atomic number 3; lightest solid element)
- Primary uses: Rechargeable battery cathode/electrolyte salt (dominant and growing); ceramics and glass; lubricating greases; pharmaceuticals
- Global production (2024 est.): ~230,000 metric tons LCE (lithium carbonate equivalent); Australia is the largest single producer by volume
- Top producing countries: Australia (~46% of global output, hard rock spodumene), Chile (~29%, brine), China (~14%), Argentina (~7%)
- Top processing countries: China dominates refining; converts ~65%+ of global lithium mineral supply into battery-grade chemicals
- Key brine regions: Salar de Atacama (Chile), Salar del Hombre Muerto / others (Argentina), Salar de Uyuni (Bolivia — large reserves but minimal production)
- Key hard rock regions: Pilgangoora / Greenbushes (Western Australia)
- Two extraction routes:
- Brine (evaporation): Lower cost, slower (18–24 months per batch), high water usage in arid deserts; dominant in South America
- Hard rock spodumene: Higher cost, faster ramp, more concentrated deposits; dominant in Australia

Supply Chain Position
Lithium feeds into the battery supply chain at multiple points:
- Lithium metal anode: Used directly by solid-state battery companies as the anode material — Factorial Energy, QuantumScape, Adden Energy, Solid Power, ProLogium all use lithium metal anodes. This requires battery-grade lithium metal (higher purity than standard chemical-grade lithium).
- Electrolyte salts: Lithium hexafluorophosphate (LiPF₆) in liquid electrolytes; lithium-based salts in solid electrolytes.
- Lithium sulfide (Li₂S): Precursor for sulfide solid electrolytes — produced by Idemitsu Kosan (¥21.3B plant, 1,000 MT/year by June 2027). Requires high-purity lithium input.
- Cathode materials: Lithium is a component of all cathode active materials — NMC, NCA, LFP, and the emerging solid-state cathode chemistries.
Documented company supply relationships: No company in this knowledge base has publicly disclosed a specific raw lithium supply agreement. Factorial Energy’s partnership with POSCO Future M for cathode/anode materials is the closest upstream relationship documented; POSCO Future M sources its own lithium inputs independently.
Geopolitical Risk Assessment
Mining concentration is moderate — Australia and Chile are broadly friendly to Western battery supply chains, and Australia’s hard rock spodumene can be refined domestically or shipped to Western processing facilities.
Refining concentration is the primary risk: China controls ~65%+ of global lithium chemical processing (conversion to LiOH and Li₂CO₃). Even lithium mined in Australia often passes through Chinese conversion facilities before reaching Western battery factories. This is why US and EU battery supply chain policy (IRA, CRMA) specifically incentivizes non-Chinese processing capacity.
Outlook: Multiple Western lithium chemical projects are underway (Albemarle’s US Kings Mountain mine restart; POSCO and LG Chem refining investments in North America), but significant non-Chinese processing capacity at scale is still several years away as of 2026.
