Processing and Recycling platform for improving lithium-ion battery sustainability

  • Experimental study and modelling of the synergistic effects in mixed collectors systems, especially with non ionic reagent
  • Development of modelling tools to describe solvent extraction of metals in mixers-settlers depending on flowsheets, flowrates and chemistry
  • Development of breakthrough process involving new chemistry relying on supercritic fluids, ionic liquids, micro and milli-fluidic devices

Project NeW-Bat
(supported by BMBF)

  • Efficient recycling of end-of-life lithium-ion batteries and production residues
  • Main item of the new recycling process is the materials selective fragmentation EHF based on shock waves
  • Goal is the complete recovery of all battery materials (especially lithium metal oxides) for direct reuse in new batteries

Project AutoBatRec 2020
(supported by EIT RawMaterials)

  • AutoBatRec 2020 will address the challenges of integrating Li-ion-batteries into a circular economy
  • It will give insight into several new developments and technologies for battery disassembly and recycling
  • Goal is a complete process concept for the upscaled disassembly of batteries as well as the fragmentation and separation into clean materials fractions
