MIT researchers have developed a low temperature process to extract battery-grade lithium from spodumene, the most common type of mineral containing lithium, using a reusable liquid reagent, writes Electronic Design’s Lee Goldberg. “The new process uses a liquid reagent to dissolve the rock into the useful forms of its constituent parts — not just battery-ready lithium salts, but also smelter-grade alumina and cement-ready silica,” writes Goldberg. “After the minerals are extracted, the solvent and reagent can be recovered and used again so that waste levels approach zero.”
