Unlocking the potential of sustainable and solvent-free fabrication of electrodes for Li-ion battery cells - ULTRADRY

Project summary

Rationale / Needs to be addressed Addressing climate change, Europe's Green Deal pledges a climate-neutral society by 2050. Herein, batteries that are more sustainable throughout their life cycle are key. Objectives The overall objective of ULTRADRY is to contribute to achieving this, by developing the fundamental understanding necessary to unlock the potential of dry processing of Li-ion battery (LIB) electrodes and reducing the F-content in the binder and electrolyte. Potential applications Although ULTRADRY is working in relatively low TRL (2-4), the developed technologies, if successful, have the potential to be readily implemented into European battery production. Impact and potential benefits Dry processing of battery electrodes is estimated to give 47 % in energy savings and 10-15 % reduced cost for battery production compared to conventional wet slurry casting. It could also produce thicker electrodes with higher energy density and improved mechanical properties.
