摘要

This poster shows, how the large-scale production process of automotive lithium-ion-batteries will evolve up to the point when a next-generation technology will be present. By comparison with other next-generation technologies, as lithium-sulfur and lithium-air, the role of the all-solid-state technology for automotive applications is investigated. The production process for all-solid-state battery cells, based on current knowledge, is displayed and the most crucial challenges for implementing the process are highlighted. Looking at the demand for Li-ion batteries in electromobility, the production process for battery cells is going to be marked by large-scale mass production. Electrode production, cell assembly and the formation/aging processes consist of multiple production steps, each facing upscaling efforts to meet the demand of the automotive industry. At the same time, high-technology materials will further increase requirements on quality and precision of the production. New technologies need to be implemented into the process to make each process step compatible with optimized Li-ion batteries and high production speeds. The range of technologies for improving the production includes laser applications in cutting and drying and new stacking methods. Meanwhile battery chemistry is optimized by nickel-rich cathodes and Si-containing anodes. At some point within the next decade the production process and the Li-ion battery itself won't have much optimization capacity left. Simultaneously, next-generation technologies, like all-solid-state, lithium-sulfur, lithium-air will improve further, possibly unlocking their high theoretical performance parameters. This technological leap will have a huge impact on the production process, making entire production steps obsolete and changing others. Therefore, new production technologies need to be researched and applied to introduce next-generation batteries, like all-solid-state, to the automotive market. To reduce costs, new production processes need to be cheap and scalable, competing with the optimized future LIB production process. The display of the current production process is the product of literature research and first hand industry information. Predicting next-generation technologies is largely based on P3 experts' opinions and continuously updated. The poster gives information on production steps, helping understand the challenges of developing a new production process. By showing the development of the LIB technology over the next years, it is possible to give a prediction on which next-generation technology will be compatible within the next decade and on what price level future BEV battery cells will be produced.
