BenchBatt – Process based energy optimization and validation of Lithium-Ion and Lithium-Sulfur battery electrodes

Funded by BMBG

Contact Person :

Summary of the project:

Content of the joint research project BenchBatt is the procedural optimization and validation of improved Lithium-Ion (LIB) and new Lithium-Sulfur (LiS) battery electrodes. Scope is the establishment of benchmarks to show the state of the art performance of LIB electrodes to compare it to materials of next generation LIB technologies.
For LiS technology, preferential for manufacturing of sulfur-cathodes in a continuous scale, current trend for materials as well as electrodes design are under examination. With this research potentials and key aspects of the LiS technology should be identified to qualify it for future fields of application.

Figure 1: Which battery technology will meet the requirements for future application?

Objectives and tasks of the iPAT

Lithium-Ion battery technology

  • Increase content of active materials and mass loading for LIB cathodes and anodes to raise the energy density
  • Special focus on the resulting limitations on electrode level with commercial available active materials
  •  
    Lithium-Sulfur battery technology

  • Sulfur-cathodes manufactured in continuous scale to compare it to current published research
  • Validation of published materials potentials from a procedural point of view
  • Adaption of material concepts for continuous electrode manufacturing processes
  •
