In ACROBAT, VITO n.v. (coordinator; VITO, BE), ENEA (ENEA, IT), the Fraunhofer Institute for Laser Technology (ILT, DE), the SIM2 institute of the university KU Leuven (KUL, BE), and the battery recycler ACCUREC Recycling GmbH (ACC, DE) will research and develop innovative and environmentally-friendly recycling technologies dedicated to spent lithium iron phosphate (LFP) batteries. The ACROBAT process will enable the recovery of ≥90% critical raw materials (Li, P, graphite) and aims for direct recycling of electrolyte, graphite and LFP cathode materials.
Currently, no dedicated, economically-viable, industrial-scale process exists to recycle end-of-life LFP-type lithium-ion batteries (LIBs), even though the market for LFP LIBs is predicted to grow exponentially. Therefore, the specific ACROBAT objectives are to develop and test
- dedicated dismantling and pre-treatment (ACCUREC)
- extractive recovery of electrolyte materials (ENEA)
- in-line characterisation of black mass (Fraunhofer ILT)
- recovery of graphite (SIM2 and VITO); hydrometallurgical lithium recovery and conversion into battery-grade lithium hydroxide monohydrate (SIM2)
- direct recycling of spent LFP cathode material into virgin LFP (VITO).
