- Scientists just found a faster, cleaner way to extract lithium for EV batteries
Scientists at Columbia Engineering have developed a new method to extract lithium from salty underground brines using a temperature-sensitive solvent, bypassing the need for water-intensive evaporation ponds. The technique is faster and can utilize low-quality lithium sources, addressing a major challenge in clean energy production.
