Lithium extraction breakthrough and Argentina's resource power gap

An opinion piece warns that Argentina’s large lithium reserves do not automatically translate into economic or geopolitical power. The country sits in the lithium triangle with Chile and Bolivia, but most value is captured downstream in processing, battery manufacturing and technology, sectors dominated by China, the United States and Europe. The article argues that without a strategy to control the full value chain, Argentina risks remaining a raw‑material supplier.

Separately, researchers at Columbia University have demonstrated a new extraction method called S3E that uses a temperature‑responsive solvent to isolate lithium directly from brines. Laboratory tests on simulated Salton Sea brine recovered about 40% of the lithium in four cycles, with ten‑fold selectivity over sodium and twelve‑fold over potassium, while eliminating magnesium. The technique avoids large evaporation ponds, reduces water use and waste, and could be powered by industrial waste heat or solar energy, promising a faster, cheaper and greener supply of lithium for the expanding electric‑vehicle and storage markets.
