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

How will the ULTRADRY partners work to reach the project’s objectives?

The research activities in ULTRADRY is divided into four scientific work packages (WPs), each lead by one of the four project partners with the aim to optimize the battery fabrication process and performance, and to improve process sustainability, as illustrated in the schematic. 

SINTEF will investigate these dry processing methods for making battery electrodes with the aim of building fundamental understanding within the field and ultimately improve the processes. Additionally, the proposed dry processing methods often require fluorine-rich binders , so SINTEF will also investigate the possibility of using binders with lower fluorine content.

Warsaw University of Technology (WUT) will focus on developing new electrolyte salt additives for the battery electrolyte with lower fluorine content. WUT will also perform  the electrochemical testing of battery cells developed in the project.

IREC will perform life cycle assessment and techno-economic analyses to qualitatively and quantitatively evaluate the benefits of dry processing of battery electrodes in general and the developed fluorine-reduced binder and electrolyte systems specifically.
