MiKal

Optimal electrode structure and density by design of mixing and calendering procedures (MiKal)

Funded by BMBF

Summary of the project:MiKal is a project within the BMBF-funded ProZell Competence Cluster. This project focuses on the determination of the interaction of mixing processes, the resulting machine and product calendering behavior as well as the generated and performance-determining microstructure of the electrodes. This should enable the identification of optimal calendering conditions and the prediction of both the machine settings and product structure settings. The interdependency between mixing and calendering process is emphasized with the aim to achieve volumetrically higher energy densities with high performance.
