ARTEMYS – Scalable, cost-effective production technologies for composite kathodes and electrolyte separators in all-solid-state batteries

Funding sponsor: BMBF

Contact : Peter Michalowski

Summary of the overall project:

Lithium-ion batteries with solid electrolytes are promising candidates for safe energy storage devices with high specific energies. The concept of these all-solid-state batteries (ASSBs) has been established at the laboratory scale with fast ion conductors based on oxidic as well as sulfidic materials. Nevertheless, there are still a lot of hurdles for upscaling the synthesis routes, which is needed for the application in electromobility applications. In the ARTEMYS project the two distinct material concepts (oxidic and sulfidic ion conductors) should be evaluated regarding feasibility for industrial mass production. Based on preliminary studies of the project partners on these materials, large scale manufacturing technologies should be established.

Objectives and tasks of the iPAT:
The focus of the subproject lies on the sulfidic solid electrolyte. Lithium thiophosphates as promising materials with high lithium ion conductivity should be used to investigate scalable production methods for cathodes and separators. By employing pure lithium metal as anode material, the energy density could be increased compared to conventional lithium ion batteries. Specific objectives herein are:

  • Development of a tape casting technique for cathode and separator slurries (identification of the ideal composition and critical process parameters)
  • Characterization of the microstructure and correlation with the resulting electrochemical properties of the battery components
  • Production of full cells with lithium metal anodes and evaluation of the functionality
  • Stacking of several cells to battery stacks with a capacity of around 1 Ah
