The aim of the project is experimental quantization of SEI and dendrite growth on metallic lithium surfaces and the implementation and integration of the growth mechanisms into a simulation software based on physical and electrochemical processes. The empirical principles and parameters obtained from the experimental analysis are incorporated into the modeling and simulation of the processes. In future, the software will be used as an emulator in Hardeware-in-the-Loop (HiL) test beds for verification of battery management system (BMS) algorithms.

Application Potential

  • Experimental methods for quantization of SEI and dendrites.
  • cell manufacturers
  • Battery manufacturers
  • Suppliers of battery manufacturers (electrolytes, electrodes, separators, binders, etc.)
  • Battery management system (BMS) manufacturers
  • Battery operating strategies ,electromobility/eMobility, renewable energy storage, etc.)
  • R&D in the field of lithium/sulfur, lithium/air and solid-state lithium-ion batteries
