The RESPECT project aims at transforming the batteries’ recycling process and at opening new sustainable and circular markets in Europe along the Li-ion batteries value chain, thus reinforcing security of supply and its strategic autonomy. RESPECT process considers the variability of Li-ion batteries chemistries (NMC, LFP, NCA, LMO), states (aged, damaged, EoL, scraps) and applications (EV, Energy Storage System [ESS]). The holistic approach covers all Li-ion recycling value chain from logistics, sorting and classification of the feedstock, to the design and integration of new recycling unit processes that aim at recovering the highest amount of resources present within Li-ion batteries. It proposes a logical chain of disruptive, flexible, sustainable and versatile recycling processes considering safety aspects for opening and deactivation and addressing full hydrometallurgy or direct recycling, depending on the targeted LiBs to be treated, supporting the development of the next generation of batteries materials.
