摘要：Given the critical requirements of environmental preservation and resource reutilization, the recovery of lithium from spent lithium-ion (LIBs) batteries holds immense significance. This study investigates the viability of nanofiltration (NF) membranes for selectively separating lithium from spent LIBs leaching solution. A membrane based approach uniquely sidesteps the significant metal losses often encountered in traditional methods that necessitate initial pH adjustments. The NF270 and DK membranes were characterized and evaluated. DK demonstrated superior rejection capabilities for high-valence metal ions with over 99.0 % rejection, while allowing a notable 40.1 % lithium passage rate. Furthermore, DK showcased enhanced acid resistance compared to NF270. The findings underscore the characteristics essential for NF membranes in this application, and the study affirms the feasibility of membrane-based lithium recovery, marking a stride in battery recycling research.
