Different cell types
The main application for lithium-ion battery packs is electric mobility. Though there are three types and formats in use, the functional principle of all types is essentially the same. The main differences are in the design, requirements, and materials used.
Battery cell manufacturing involves four main process steps
Lithium-ion battery cell production consists of four main process steps: electrode production, cell assembly, cell finishing, and battery pack assembly. The electrode production and cell finishing process steps are largely independent of the battery cell type, while cell assembly distinguishes between pouch or prismatic cells and cylindrical cells. Regardless of the cell type, the smallest unit of any lithium-ion cell consists of two electrodes and the separator that divides them from one another. In between is the ion-conducting electrolyte.
Machine vision ensures product quality and process stability
Machine vision systems provide valuable information during the production process, including inspecting materials and ensuring process steps are correctly executed. Different solutions are available depending on your application needs. By combining our frame grabber-based systems with VisualApplets and our high-sensitivity line scan cameras, the resulting vision system can easily cope with the high speeds found in electrode production. High-resolution ace 2 X visSWIR cameras inspect the structures of separator foils inside the cell. Our area scan cameras, working in conjunction with pylon vTools, check that the cathode and anode are correctly positioned on top of each other during the winding of prismatic cells. Catching even the smallest defect is critical, since accurate error tracking increases productivity.
