Researchers develop polyurea membranes for lithium recovery from waste batteries

In a study published in the Journal of Membrane Science, a research group led by Prof. Wan Yinhua from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences propose a new zone-regulated interfacial polymerization strategy, aiming to fabricate acid- and alkali-resistant nanofiltration (NF) membranes with high separation selectivity for the lithium recovery from waste lithium batteries.
