2023 AUG 21 (NewsRx) -- By a News Reporter-Staff News Editor at Nanotech Daily -- New research on Nanotechnology - Supramolecular Research is the subject of a report. According to news originating from Nanchang , People’s Republic of China , by NewsRx correspondents, research stated, “Extraction and recovery of lithium from reserves play a critical role in the sustainable development of energy due to the explosive growth of the lithium-battery market. However, the low efficiency of extraction and recovery seriously threatens the sustainability of lithium supply.”

Financial support for this research came from Key Technologies Research and Development Program.

Our news journalists obtained a quote from the research from Nanchang Hangkong University , “In this contribution, we fabricate a novel mechanically robust fluorine-rich hydrogel, showing highly efficient Li extraction from Li-containing solutions. The hydrogel was facilely fabricated by simple one-pot polymerization of supramolecular nanosheets of fluorinated monomers, acrylic acid and a small amount of chemical crosslinkers. The hydrogel exhibits a remarkable lithium adsorption capacity (Q Li =122.3 mg g ) and can be reused. Moreover, it can exclusively extract lithium ions from multiple co-existing metal ions. Notably, the separation of Li /Na in actual wastewater is achieved with a surprising separation factor of 153.72. The detailed characterizations as well as calculation showed that the specific coordination of Li-F plays a central role for both of the striking recovery capability and selectivity for Li. Furthermore, an artificial device was constructed, displaying high efficiency of extracting lithium in various complex actual lithium-containing wastewater.”

According to the news editors, the research concluded: “This work provides a new and promising avenue for the efficient extraction and recovery of lithium resource from complex lithium-containing solutions.”

This research has been peer-reviewed.
