Already, the four companies that in 2015 provided 88 percent of the world’s lithium can’t keep up: Lithium contract prices have increased from $4,000 per metric ton in 2014 to as high as $20,000 today. ... That’s why a host of junior entrants are scrambling to get into the game. Whoever can figure out the extraction and chemistry required to get lithium out of the ground and into batteries stands to capture a significant share of the market. But as with any commodity, it’s a precarious business. ... Lithium can be mined from rocks, as in Australia and China, but in Clayton Valley and the lithium triangle it’s extracted from briny aquifers. ... The best hope new entrants have of catching Albemarle lies in a process being developed by Tenova SpA, an Italian engineering company. This method, which strips the lithium using an ion-exchange system and returns the water to the ground, would allow companies to skip evaporation ponds, slashing production time from months to hours while yielding a higher concentration of lithium.
