Key Points

This research aims to model the extrusion process for manufacturing lithium-ion battery electrodes using a discrete element method.
Utilized a discrete element method model for simulating the extrusion process.
Employed a twin-screw extruder for dry mixing to create battery electrode filaments.
Highlighted the microstructure of the extruded filaments and their application in 3D printing.
Demonstrated effective modeling of the extrusion process for enhanced battery electrode production.
Showed the microstructure of the filaments supports their use in 3D printing applications.

Abstract

The Cover Feature illustrates the manufacture of filaments by a dry mixing process using a twin-screw extruder; they are subsequently used for 3D printing lithium battery electrodes. The graphic highlights a discrete element method model of the extruder with a recirculation structure, the microstructure of the extruded filament, a spool of 3D-printing filament, and a conceptual representation of a 3D-printed battery.
