Fertigung von Lithium-Ionen-Batteriezellen

In der Verwendung von Augmented Reality in der Industrie steckt enormes Potenzial. Besonders der Einsatz von Datenbrillen bietet den Vorteil, dass beide Hände frei für die Arbeitsaufgabe sind. Informationen stehen jederzeit optisch zur Verfügung. Perspektivisch werden Akteure in der Industrie virtuelle mit realen Bauteilen kombinieren und am virtuellen Objekt trainieren können. Besonders schwierige Aufgaben können ebenfalls zunächst virtuell ausprobiert werden. Dies sind nur einige der vielen Einsatzmöglichkeiten, die entwickelt werden. Dem praktischen Einsatz von Datenbrillen stehen neben Herausforderungen in der Softwareentwicklung aber auch ganz handfeste Probleme entgegen, über die man sich Gedanken machen sollte, bevor in Augmented Reality investiert wird. So sind z. B. Gleitsichtbrillen, die immerhin ein Viertel aller in Deutschland getragenen Brillen ausmachen, derzeit nicht immer mit Datenbrillen kompatibel. Welche Genauigkeit erfordert eine Anwendung? Auch Fragen des Arbeitsschutzes und des Datenschutzes müssen beachtet werden. Da Datenbrillen mit einer Kamera ausgestattet sind, muss z. B. geklärt werden, unter welchen Bedingungen diese überhaupt auf dem Shopfloor gewünscht sind. Prof. Dr.-Ing. Werner Schreiber, der 15 Jahre lang in der Konzernforschung der Volkswagen AG das Forschungsfeld Virtuelle Techniken leitete, trägt mit diesem Buch dazu bei, die Beurteilungskompetenz für den Einsatz von Datenbrillen zu stärken, damit ein durchdachter und nachhaltiger Einsatz in der Industrie zukünftig möglich sein wird.

Lithium-ion batteries have become an indispensable part of everyday life. They are used in cordless screwdrivers, smartphones and earbuds, as well as in e-bikes and electric vehicles. The manufacturing of lithium-ion battery cells requires the highest level of precision, as numerous process parameters — such as ambient air conditions or the viscosity of the electrode slurry — have a significant impact. In many cases, these parameters are interdependent and strongly influence the quality of intermediate and final products. A lack of knowledge or poor decisions can result in substantial damage. This book presents the key process parameters relevant to the manufacturing of lithium-ion batteries and explains how they interact. It is aimed at process and plant planners responsible for managing the production process of lithium-ion batteries as well as planning machinery and equipment for battery cell production. Students of manufacturing engineering and electrical engineering will also benefit from the practical knowledge conveyed on this forward-looking topic. The book covers the following topics: - Structure and operating principles of lithium-ion batteries - Causes of damage and failure mechanisms in lithium-ion batteries - Production processes for electrodes and battery cells - Planning and maintenance of battery cell factories The topics of occupational safety and traceability of the materials and components used round out the content.

The use of augmented reality in industry holds enormous potential. In particular, the use of smart glasses offers the advantage that both hands remain free for the task at hand, while information is continuously available in the user’s field of vision. In the future, industrial actors will be able to combine virtual and real components and train on virtual objects. Especially complex tasks can initially be tested in a virtual environment. These are just a few of the many possible applications currently being developed. However, beyond challenges in software development, the practical use of smart glasses also faces very tangible issues that should be carefully considered before investing in augmented reality. For example, progressive lenses—which account for roughly a quarter of all glasses worn in Germany—are not always compatible with smart glasses. What level of accuracy is required for a given application? Questions of occupational safety and data protection must also be addressed. Since smart glasses are equipped with cameras, it must be clarified under which conditions their use is acceptable on the shop floor. Prof. Dr.-Ing. Werner Schreiber, who led the research field of Virtual Technologies in corporate research at Volkswagen AG for 15 years, uses this book to strengthen the ability to assess the use of smart glasses, enabling thoughtful and sustainable implementation in industry in the future.
