KonSuhl – Continuous slurry production

Funding authority: BMBF

Contact : Matthias Haarmann

Project overview:

The aim and the content of this research project, which is part of the competence cluster for battery cell production (ProZell), is the establishment of a continuous dispersing process for battery suspensions. The focus of these investigations is the comparison of different process sequences, the scalability of the process and the effects of continuous suspension production on the subsequent process steps. Furthermore, a process-structure model will be developed for the prediction of the dispersion result. The overall objective is replacing the state of the art discontinuous manufacturing process by a more economically advantageous continuous process.

Objectives and tasks of the iPAT

  • Development and adaptation of analytical methods and deriving of quality criteria for suspension production
  • Establishment and adaptation of continuous dispersing processes
  • Comparison of continuously and discontinuously prepared suspensions by means of the previously established quality criteria as well as with regard to the subsequent electrode properties
  • Proof of process capability / scalability
  • Establishment of a process structure model and process cost model
