FesKaBat- All-solid-state cathodes for future high energy density batteries

Funded by: BMWi

Contact : Laura Helmers

Summary of the overall project:

The aim of the project is the process development of all-solid-state cathode for high energy density batteries. This includes conditioning (e.g. granulation or agglomeration process, surface coating etc.) of cathode components as well as structural and electrochemical analysis of the produced composites. The obtained data will be used to develop a structural model. The targeted cell design consisting of a cathode composite and a pure lithium anode should provide a high voltage stability and cycling stability for high c-rates.
