PULSELiON publishes its 21st Open Access Paper: “Mesoscopic Model of Extrusion during Solvent-Free Lithium-ion Battery Electrode Manufacturing”
The PULSELiON project proudly presents its 21st Open Access publication, marking another milestone in the advancement of sustainable, solvent-free battery manufacturing.
The paper, titled “Mesoscopic Model of Extrusion during Solvent-Free Lithium-ion Battery Electrode Manufacturing”, was published in Batteries & Supercaps already a while ago (2024, 7, e202300441) by Wiley-VCH and is available Open Access.
A new digital modelling approach for sustainable battery electrode production
The research introduces a mesoscopic Discrete Element Method (DEM) model that simulates the extrusion step used in solvent-free lithium-ion battery electrode manufacturing. The extrusion step is a key process in next-generation electrode production, replacing the use of toxic solvents and enabling more eco-friendly manufacturing routes.
By explicitly representing the active material and binder–carbon phases, the model provides a 3D view of how parameters like extruder speed, feeding strategy, and cohesion level affect the microstructure and transport properties of the electrodes.
The results demonstrate that the model can predict key qualitative behaviors observed experimentally — such as the balance between electrical and ionic conductivity and the effects of extruder speed on particle agglomeration.
