DEPOION – Novel Technology for Deposition of LIPON Solid State Ionic Conductors for Li-Ion Batteries

The aim of the project is to combine MAR-HiPIMS technology for thin-film deposition, laser processing methods for shaping the films and removing excess material, and FAST/SPS technology for the production of targets used in deposition methods, in order to produce solid electrolytes with an ionic conductivity of approximately 10⁻⁶ S cm⁻¹.

Key stages include the production of doped LiPO targets for sputtering, the deposition of thin LiPON films using magnetron sputtering, and the use of laser technologies for ablation and cutting. The project activities aim to improve the conductivity of the targets and to investigate the effect of dopants, such as aluminium, silicon and boron, on the properties of the ionic conductor. The project involves analysing deposition methods and the influence of microstructure on cell parameters, as well as developing a prototype cell at TRL 6.

The DEPOION consortium members:

• Łukasiewicz Research Network – Poznań Institute of Technology (project leader),
• BFH Bern University of Applied Sciences (Switzerland),
• EMPA Swiss Federal Institute of Materials Science and Technology (Switzerland),
• The Batteries (Polish company).
