MIT team develops lower-cost lithium extraction method for battery materials

- MIT researchers reported a new lithium extraction approach that could make it cheaper and more energy-efficient to recover battery-grade lithium from hard rock deposits.
- The method uses a liquid solution inspired by a bathroom renovation product, works at room temperature, can be reused, and may cut costs by about half compared with current techniques.
- The advance matters because lithium supply is a key bottleneck for batteries and the energy transition, and the team says the leftover waste could be repurposed into useful materials.
- Researchers said they are now focused on scaling the process, with the goal of making extraction “the lowest-energy, lowest-cost way” to get lithium from rock.
