Advancements in recycling technologies for spent lithium-ion batteries (LIBs) are moving toward environmentally friendly and lower carbon approaches. This study presents a novel method lithium extraction from LIBs based on multipotential field membrane coupling process involving nanofiltration (NF), reverse osmosis (RO), selective electrodialysis (SED). Lithium is extracted the leaching liquor of containing multiple ions by using NF. The combined effects Donnan steric hindrance dielectric exclusion determine retention rates each ion. Divalent such as Ni2+, Co2+, Mn2+ experience stronger repulsion during mass transfer process, resulting rejection all above 98%, which advantageous separation ions, recovery rate NF stage reached 96.02%. Considering characteristics liquor, acidic high chloride, DK selected its superior comprehensive performance three commercial membranes, with particular focus assessing long-term stability tolerance. Finally, coupled RO concentration SED processes to achieve efficient enrichment lithium. 15.23 g/L, Li2CO3 product main content 99.82% prepared, providing an LIBs.
