The rise of the production of lithium-ion batteries (LIBs) calls for a global improvement of the electrode manufacturing process. At present, slurry casting is the standard technique. The solvent-free (SF) approach appears as a prominent alternative as it avoids the use of toxic solvents and decreases the environmental impact.
Extrusion-based coating is promising for the fabrication of Li-ion batteries. Improved homogeneity and negligible binder migration during fast drying procedures. Significantly reduced energy and materials demands leading to lower costs. Extended the process window for electrode design parameters.
In addition, the transferability of competencies from the production of lithium-ion battery cells is discussed. The publication “Battery Module and Pack Assembly Process” provides a comprehensive process overview for the production of battery modules and packs. The effects of different design variants on production are also explained.
The manufacture of the lithium-ion battery cell comprises the three main process steps of electrode manufacturing, cell assembly and cell finishing. The electrode manufacturing and cell finishing process steps are largely independent of the cell type, while cell assembly distinguishes between pouch and cylindrical cells as well as prismatic cells.
Recent technology developments will reduce the material and manufacturing costs of lithium-ion battery cells and further enhance their performance characteristics. With the help of a rotating tool at least two separated raw materials are combined to form a so-called slurry.
For example, first investigations indicate that the drying time of comparable electrodes can be reduced by more than 50% for electrodes prepared by the extrusion-based coating process. Furthermore, the extrusion-based coating process is expected to be less sensitive to the unfavorable effect of binder migration during the drying step.
Generally, the electrodes fabricated by extrusion and casting processes exhibit similar electrochemical performance, proving that the extrusion-based process has the technical potential to be established for electrode production.

For example, battery cells for electric vehicles vary in format and exact dimension, although usage patterns and general requirements of most electric cars might be very similar. Indeed, the technical fit alone is usually not the primary issue, but about OEMs'' strategic and long-term cooperating decisions for suppliers.
