Researchers have developed a chemical extraction system using oxybenzone and Aliquat 336 that recovers 99 percent of lithium from lithium precipitation mother liquor. This research-stage development is intended to improve the efficiency and sustainability of the global lithium supply chain.
Why it matters
Efficient extraction technologies are critical for meeting the rising demand for lithium in energy storage and battery manufacturing. This process demonstrates a pathway to high-purity lithium recovery from complex alkaline industrial waste solutions.
The system achieves a final solution concentration of 13.3 grams per liter of lithium with a residual sodium content of only 0.003 grams per liter. Thermodynamic analysis indicates the extraction is spontaneous and exothermic.
The details
The process employs a two-stage countercurrent extraction—a technique where two fluids move in opposite directions to maximize transfer—followed by two-stage cross-current water scrubbing and stripping to purify the metal. The chemistry relies on coordination and electrostatic interaction, using oxybenzone and Aliquat 336 as active agents to selectively bind and isolate lithium ions from the mother liquor, which is the remaining solution after initial precipitation.

The Tech Race
This extraction system targets the bottleneck of lithium purification within the existing industrial lithium supply chain. It marks a push to improve separation efficiency, competing with established solvent extraction methods that often struggle to achieve high purity when sodium concentrations are high.
This development is currently limited to laboratory-scale research and does not have a set timeline for commercial availability. It primarily impacts manufacturers and chemical engineers looking to improve lithium recovery yields in battery recycling or brine processing workflows.
The takeaway
The research establishes a successful chemical protocol for high-yield lithium recovery from alkaline solutions. The next critical milestone for the technology will be the transition from thermodynamic demonstration to industrial pilot testing.
