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.
