Nanofiltration

Lithium-selective nanofiltration membranes (GENF)

GreEnvi Corp. is advancing the design and manufacture of lithium-selective nanofiltration (NF) membranes for efficient lithium extraction from brine solutions, which is crucial for battery technology. These NF membranes feature nanoscale pores that selectively filter lithium ions while rejecting larger or differently charged species. Surface functionalization enhances ion selectivity and permeability. This innovation meets the growing need for sustainable lithium extraction by offering a high-performance solution that reduces energy consumption and operational costs. Designed for diverse pressure and temperature conditions, the membranes are ideal for geothermal brine treatment and lithium recycling from spent batteries, supporting the electric vehicle and energy storage industries and global sustainability efforts.
