Compared to the spin-coating method, which rapidly forms wet films by centrifugation, the film deposition process of the blade coating relies on a slower solvent evaporation rate, and making it more dependent on thermodynamic equilibrium [15] is more challenging for blade coating to fabricate crack-free and even solid films in the process of
1.Mixing. It can also be called mixing, homogenization, pulping, batching, etc. Through certain feeding sequence, stirring process, vacuum control, temperature control and other conditions, the key components such as positive and negative active substances, conductive agents, adhesives and solvents are prepared into non-Newtonian fluids with certain viscosity and particle size
Currently, the manufacturing of LIBs still needs to go through slurry mixing, coating, drying, calendering, slitting, vacuum drying, jelly roll fabrication (stacking for pouch cells and winding for cylindrical and prismatic
BMW will install a total of five cell coating lines to expand the production of components for fully electric vehicles. BMW Group has announced that its first cell coating line has gone into series operation for battery modules production at the manufacturing site in Leipzig (Germany). Over the year, the company will install other four lines, to expand the production of

Most importantly, Tesla also submitted a simplified diagram of its 4680 battery cell production process, though most of the diagram was blacked out in the revised filing''s public release.
The production of the lithium-ion battery cell consists of three main process steps: electrode manufacturing, cell assembly and cell finishing. Electrode production and cell finishing are largely independent of the cell type, while within cell assembly a distinction must be made between pouch cells, cylindrical cells and prismatic cells.
BMW Group Plant Leipzig''s first cell coating line has gone into series operation as e-component production at the site continues to gain momentum. By 2024 the two existing module assembly lines will be complemented by a third, as well as four more cell coating lines and two more high-voltage battery assembly lines.
The manufacturing process of a battery cell includes three main process steps, electrode production, cell assembly, and cell finishing. Special attention in cell manufacturing can be paid to cell finishing processes. Here, the sub-processes soaking, formation, aging, and testing are particularly time- and quality-critical process steps.
In battery manufacturing, the coating process involves evenly applying electrode slurry onto aluminum (cathode) and copper (anode) metal foils using a coater. This is followed by a drying process. In large-scale manufacturing, such as CATL's process, the coating method used is a tensioned web over slot die with backing roll.
Then other energy consumers such as the technical building services can also be included. 5. Conclusion Cell finishing is a time, energy and cost intensive process step in battery cell production. Various influencing factors such as organizational factors, process and product factors, and energy factors come together here.
Here the cell manufacturing is defined by a reference assembly line of 15 parts per minute . This line is operated daily in two shifts. The cell finishing line under consideration is fully automated in mass production and can thus be operated in three shifts. For ease of handling in cell finishing, 256 battery cells are combined into one tray.
From these scenarios, the process throughput, machine utilization, energy consumption and energy costs are simulated. For this purpose the cell finishing process chain is modeled using the discrete event simulation software Tecnomatix Plant Simulation 14.
At the same time, cell finishing is a very time-consuming and therefore cost-intensive process step in the production of battery cells and thus an important factor in reducing production costs [3, 4, 5, 6]. Current publications show that the share of production cost for cell finishing varies between 20% and 30% [4, 7].
