Introduction
Can nanofiltration membranes selectively recover lithium from spent lithium-ion batteries?
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.
Do lithium-ion batteries have a separator membrane?
Provided by the Springer Nature SharedIt content-sharing initiative Lithium-ion batteries (LIBs) with liquid electrolytes and microporous polyolefin separator membranes are ubiquitous. Though not necessarily an active component in a cell, the separator plays a key role in ion transport and influences rate performance, cell life and safety.
Does a positive charge membrane help to recover monovalent lithium ion?
Therefore, when separating spent LIBs leaching solution with a pH value of 1, the positively charged surface of these membranes would facilitate the rejection of high-valence metal ions through the Donnan effect, ultimately achieving the recovery of monovalent lithium ion.
Why is DK membrane important for lithium ion recovery?
DK membrane exhibits excellent acid resistance and high-valence metal ion rejection to the leaching solution. Given the critical requirements of environmental preservation and resource reutilization, the recovery of lithium from spent lithium-ion (LIBs) batteries holds immense significance.
How does a lithium membrane improve the permeability of a leaching solution?
As a result, the membrane's selectivity towards lithium ions is enhanced by increasing the rejection of higher-valence metal ions, improving the separation of lithium from other impurities in the leaching solution. It should also demonstrate excellent acid resistance to ensure long-term operational stability.
