At a time when electrified vehicles and stationary energy storage play key roles in the climate-neutral future of the energy sector, sustainable production of lithium-ion batteries is essential. A team of researchers headed by Benjamin Schumm, Holger Althues and Stefan Kaskel has developed DRYtraec (dry transfer electrode coating), a novel method of battery cell production that uses none of the toxic solvents that are otherwise typical and eliminates the energy-intensive and costly drying of the electrode layers.
