Mem4Bat: Sustainable membrane-based recovery of for battery manufacturing
The rapid growth of liquid-ion battery (LIB) production is driving demand for purer N-Methyl-pyrrolidone (NMP), a key solvent used in manufacturing cathodes. While current recovery solutions exist, they can’t meet the stringent purity standards required for reuse in LIB production due to metal contamination. This is where Indaver steps in with an advanced purification process capable of achieving battery-grade NMP.
Through the Mem4Bat project, Indaver and VITO are building on previous successes to develop cutting-edge membrane technologies like organic solvent nanofiltration (OSN), aiming to remove metal contaminants at sub-ppb levels. With promising early results, this project is tackling the significant challenge of long-term membrane stability in aggressive solvents, setting the stage for more sustainable and efficient NMP recycling in the growing battery industry.
