MultiDis – Multiscale approach for the description of carbon black deagglomeration in the dispersion process for a process and performance-optimized process control

Funded by BMBF

Contact Person : Julian Mayer

Summary of the overall project:

MultiDis is a project within the BMBF-funded ProZell Competence Cluster. The main topic of the investigations is the dispersing process of lithium-ion battery slurries. By a coupled CFD-DEM simulation and its experimental validation via suspension and electrode properties (including investigation and reconstruction of the microstructure), the dispersing process in the planetary mixer is optimized with regard to the carbon black structure, the dispersion time and the energy requirement. In accordance with the objectives of the cluster, the focus is on the resulting quality and performance of the cells as well as their costs.

Objectives and tasks of the Institute for Particle Technology

  • Preparation and characterisation of suspensions in a planetary mixer
  • Implementation of additional analytics for the dispersing process
  • Development of a sample preparation method for direct structural analysis
  • Production of electrodes by continuous coating and macroscopic characterization with respect to the carbon black structure
  • Electrochemical examination of the electrodes via test cells
  • Simulation of the dispersing process on the macro scale as a function of fluid properties and process parameters
  • Numerical based optimization of the dispersing process at pilot and pilot plant scale
