Lithium Mining Is Spread Out, Lithium Chemical Conversion Is Not

Lithium’s supply chain follows the same pattern documented on cobalt’s and copper’s supply chain pages, mining spread across several countries, processing concentrated in one, and the specific mechanics of that split are worth naming precisely.

Mining: genuinely multi-country

Lithium mine production draws from Australia’s hard-rock pegmatites and the Lithium Triangle salars spanning Chile, Argentina, and Bolivia, with meaningful output from several other countries too. At the mining stage alone, lithium is more geographically diversified than cobalt, no single country plays the role DR Congo plays for cobalt mining.

Chemical conversion: the real chokepoint

The bottleneck sits one step downstream: converting spodumene concentrate or brine-derived lithium into the battery-grade lithium carbonate or lithium hydroxide a cathode maker actually needs requires dedicated chemical conversion capacity, and a large majority of the world’s lithium chemical conversion capacity has been built in China, including facilities that process spodumene concentrate shipped there specifically from Australian mines. This means Australian-mined lithium routinely travels to China to become the chemical form batteries actually use, a real, physical dependency that mine-level production statistics alone do not show.

Emerging efforts to build alternative capacity

Governments and companies in the US, Europe, and elsewhere have announced real, if still comparatively small, investments in domestic lithium conversion capacity specifically to reduce this dependency, a genuine, current response to the concentration described above, though one still in an early, unproven stage relative to the scale of existing Chinese conversion capacity.
