The anode and cathode materials are mixed just prior to being delivered to the coating machine. This mixing process takes time to ensure the homogeneity of the slurry. Cathode: active material (eg NMC622), polymer binder (e.g. PVdF), solvent (e.g. NMP) and conductive additives (e.g. carbon) are batch mixed. The anode and cathodes are coated separately in a continuous coating process. The cathode (metal oxide for a lithium ion cell) is coated onto an aluminium electrode. The. The electrodes up to this point will be in standard widths up to 1.5m. This stage runs along the length of the electrodes and cuts them down in width to match one of the final dimensions required for the cell. It is really important that no burrs are created on the edges of. Immediately after coating the electrodes are dried. This is done with convective air dryers on a continuous process. The solvents are recovered.

Are competencies transferable from the production of lithium-ion battery cells?
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 main component of traction batteries is the battery cells, which make up about 55-60 % of the total weight in a battery pack used in mid-sized BEVs (e.g., Nissan Leaf, VW e-Golf, electric Ford Focus) ( Ellingsen et al., 2014;).
What are the components of a battery?
The remaining battery components are: the module and pack enclosure (32-38 % of the total battery weight), the thermal management system (3 %), the battery management system (BMS; 3 %) and the electrical system (1 %) ( Ellingsen et al., 2014;). The processes associated with battery production are shown in Figure 1 and described below.
The Battery Production specialist department is the point of contact for all questions relating to battery machinery and plant engineering. It researches technology and market information, organizes customer events and roadshows, offers platforms for exchange within the industry, and maintains a dialog with research and science.
