Circular economy and electrical mobility: functional recycling by electro-hydraulic fragmentation, electro-leaching and anti-solvent precipitation of lithium-ion batteries

In a context of the electrification of the Belgian and European motor vehicle fleet, the recycling of end-of-life Li-ion batteries has become a major issue of concern. The CTP has joined forces with the university laboratories GeMMe and GreenMat to propose an innovative recycling process, implementing a fragmentation technique which should enable a better separation of the battery’s various components, and hydro-metallurgical techniques more sparing of reactants and of energy to recover the metals contained in the black mass. The objective is to move towards the production  of precursors for the manufacture of new cathodes. The key stages of the process are currently undergoing experiments at the laboratory level.
