Abstract:
The urgent need to reduce global greenhouse gas emissions and transition to an energy matrix centered on renewable energy guarantees a steady demand for lithium, but speculation that South America is on the cusp of a lithium boom is premature. The chemical is critical in the production of rechargeable batteries for mobile devices, electric vehicles, and, increasingly, renewable energy storage systems. The so-called Lithium Triangle of Argentina, Bolivia, and Chile holds just over half the world’s currently known lithium deposits, while Brazil and Peru have large amounts of spodumene hard rock that contains lithium.
- Lithium in its natural form is part of a chemical compound that requires a complex re-composition process to make, among other things, lithium‑ion battery cells. How it is mined entails significant cost differences. Lithium from the brine below salt flats in Argentina and Chile is currently the most cost-competitive. While Bolivia also has brine deposits, the lithium is less concentrated, contains more impurities, and is found at more difficult-to-access lower depths in the Uyuni salt flats. Accessing lithium in spodumene hard rock pegmatites is even more complicated and hence costlier. The advantage, though, is that this type of lithium synthesizes better with the higher nickel content required to improve electric vehicle performance and range.
The region’s largest producers adopted different approaches to capitalizing on lithium reserves.
- In 2008, then-President Evo Morales of Bolivia restricted extraction to the state-owned Corporación Minera de Bolivia (COMIBOL) because past commodity boom and bust cycles profited foreigners and left little wealth but plenty of environmental catastrophes and other social ills in their wake. In 2017, lithium extraction was transferred to the newly created Yacimientos de Litio Bolivianos (YLB). Morales also promoted public-private partnerships to jointly produce batteries and even electric vehicles in Bolivia. The latter echoes a failed Andean Pact initiative during the 1970s in which aspects of automobile production were to be distributed among different member states. The scheme failed because, among other reasons, manufacturing anything in isolated Bolivia was cost prohibitive due to poor infrastructure. Several decades later, logistical realities still make exporting a Bolivian-produced electric vehicle, let alone lithium‑ion batteries, economically unfeasible.
- Chile, which also deems lithium to be a strategic mineral, imposes onerous production quotas on private-sector producers and requires that they sell 25 percent of their output at preferential rates to domestic downstream buyers. The set-aside provision is designed to encourage manufacturing in Chile of lithium‑ion battery components such as cathodes, hydroxide, and electrolytes. While Argentina is more accepting of private investment in its lithium industry, the country is notorious for recurring economic crises and erratic oscillation in economic policy that make investing in the country a high-risk proposition.
