A new process for recycling production scrap from the dry manufacturing of lithium-ion batteries has been created at the MEET Battery Research Center of the University of Münster in Germany.
In conventional battery production, active cathode materials are mixed into a slurry with solvents and coated onto an aluminum current collector. This process uses the solvent N-methyl-2-pyrrolidone (NMP) and polyvinylidene fluoride (PVdF) as a binder. Afterwards, the coated electrode must undergo an energy-intensive drying process, and the evaporated solvent must be recovered via an elaborate process.
