The ‘Production Process of a Lithium-Ion Battery Cell’ guide pro-vides a comprehensive overview of the production of different battery cell formats, from electrode manufacturing to cell assembly and cell finishing. Furthermore, current trends and innovation of different process technologies 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.
The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.
Figure 1 introduces the current state-of-the-art battery manufacturing process, which includes three major parts: electrode preparation, cell assembly, and battery electrochemistry activation. First, the active material (AM), conductive additive, and binder are mixed to form a uniform slurry with the solvent.
The production processes are listed below and are primarily divided into a wet process based on PE and a dry process based on PE or PP. Eventually, a typically ceramic composite is applied to the separator with an engraving roller to meet the requirements of a lithium-ion battery. The PE-based wet process is the most widely used production method.
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.
