Twin-Screw Extruder-Driven Dry Coating: A Leap in Sustainable LIB Electrode Production
Twin-Screw Extruder-Driven Dry Coating: A Leap in Sus-tainable LIB Electrode Production
The booming EV market drives the demand for LIBs, which face three main challenges: lowering production costs, enhancing battery performance metrics, and en-suring sustainable component manufacturing. To ad-dress these challenges, manufacturers are dedicating enormous R&D efforts to switch to dry electrode coating and replace the traditional wet, slurry-based methods. This innovative approach eliminates hazardous solvents, cuts costs, and improves battery performance. It forms a cohesive matrix directly from powder components, mak-ing the process more sustainable and efficient, while supporting high-loading dry battery electrodes (DBEs).
In this context, the twin-screw extruder is crucial for pro-ducing battery masses. Anton Paar's laboratory and pilot extruders, with capacities ranging from 0.060 kg/h to 100 kg/h, facilitate the development and optimization of dry coating processes at both laboratory and pilot plant scales. This sets the basis for successful upscaling to full DBE production.
