Will the World's Lithium Suppliers Slow Production of Electric Vehicles?

Slashdot reader atcclears quotes the Wall Street Journal:Hailed as the Saudi Arabia of lithium, this California-sized chunk of terrain [in Salar de Atacama, Chile] accounts for some 55% of the world's known deposits of the metal, a key component in electric-vehicle batteries. As the Chinese EV giant BYD Co. recently learned, tapping into that resource can be a challenge. Earlier this year, after BYD won a government contract to mine lithium, indigenous residents took to the streets, demanding the tender be canceled over concerns about the impact on local water supplies. In June, the Chilean Supreme Court threw out the award, saying the government failed to consult with indigenous people first.... Similar setbacks are occurring around the so-called Lithium Triangle, which overlaps parts of Chile, Bolivia and Argentina. Production has suffered at the hands of leftist governments angling for greater control over the mineral and a bigger share of profits, as well as from environmental concerns and greater activism by local Andean communities who fear being left out while outsiders get rich. At a time of exploding demand that has sent lithium prices up 750% since the start of 2021, industry analysts worry that South America could become a major bottleneck for growth in electric vehicles. "All the major car makers are completely on board with electric vehicles now," said Brian Jaskula, a lithium expert at the U.S. Geological Survey. "But the lithium may just not be enough." Meanwhile, a chemical engineering professor at Indiana's Purdue University has spent years looking for an alternative to lithium batteries, and their researchers are now testing sodium carbonate and the possibility of sodium ion batteries.
