EVOLi²S – Evaluation of the technical and economic advantages of the open-cell module for lithium-ion and lithium-sulphur batteries with regard to stationary and mobile applications

Funded by: BMBi

Contact person : Robin Moschner

Summary of the project:

The project focuses on a new cell design (“Open Cell Module”, OCM), the application of which is being investigated with regard to the performance and economy of lithium-ion (LIB) and lithium-sulfur (LSB) batteries in stationary and mobile applications. Comparing the results with those of a pouch cell system, the aim is to determine the most advantageous cell system in terms of specific energy, cycle stability and lifetime. The technical feasibility will be evaluated and the economic feasibility in mobile and stationary applications will be considered based on adapted battery sizes. In addition, it will be clarified to what extent the costs of component production can be reduced compared to current processes. For example, to increase the production speed, a new type of slot dies and drying technologies for the electrode production will be investigated.

Objectives and tasks of the iPAT

  • Determination of an improved coating process for LSB cathodes based on S/C composites based on the comparison between comma bar and slot die technologies
  • Comparison of a convective and diffusive drying process of electrodes
  • Production of the LIB electrodes as a reference system
  • Formulation strategies and continuous suspension production using an extruder
