The world contains vast quantities of lithium, an integral element in electric vehicle batteries. And though lithium is commonly mined from hard rock, the majority of the world's lithium reserves are actually found in brine, extremely salty water beneath the Earth's surface.Today, brine mining involves evaporating the brine in massive, extravagantly colored pools over a series of about 18 months, leaving high concentrations of lithium behind. It's a simple but inefficient process that takes up vast swaths of land and is…
