Nanofiltration membrane has been developed specifically targeting Direct Lithium Extraction (DLE) from brine, since the demand for lithium–ion batteries continues to grow following the global trends toward decarbonization and electrification. This increasing demand necessitates DLE from more readily–available and environmentally–friendly methods compared to traditional open–pit mining. Our newly–developed nanofiltration element “FilmTecTM LiNE–XD” enables high lithium passage from typical chloride–rich Li–brine streams and an excellent selectivity over divalent metals such as magnesium. In addition, LiNE–XD provides robust and reliable operations with long–lasting service time under minimized energy consumption; > 30% energy saving compared to other options.
