Thermoresponsive solvents for efficient lithium extraction
This technology is a technique to selectively extract lithium from brine streams using thermoresponsive solvents.
Unmet Need: Environmentally friendly, cheap, and efficient method for lithium extraction
Portable electronics and many materials rely heavily on lithium. However, lithium is often found in brines alongside many similar elements, rendering its extraction challenging. Current methods for extracting lithium suffer from high costs, low efficiency, and adverse environmental effects. Thus, there is a need for more efficient methods to extract lithium from brines while minimizing the environmental impact.
The Technology: Thermoresponsive solvent system for lithium extraction
This technology is a method that extracts lithium from other salts, such as potassium and sodium, using a thermoresponsive solvent system. Lithium preferentially partitions into the organic phase of the solvent and can then be extracted from it by heating. Initial experiments show selectivities of 7.7x over sodium and 7.8x over potassium ions.
Applications:
- Lithium extraction from brines
- Extraction and purification of other metals from aqueous sources
- Wastewater treatment
- Electronics recycling
Advantages:
- Efficient lithium extraction from brine
- Easy separation using thermoresponsive nature of solvent
- Potential for reduced costs and environmental impact
