Descrizione del progetto
Affrontare la crisi dei rifiuti di batterie con soluzioni sostenibili
Con la crescente necessità di una gestione efficace dei rifiuti di batterie, le batterie agli ioni di sodio, NMC e LFP contribuiscono in modo significativo a questa sfida, in quanto rappresentano l’85 % del problema. I tradizionali metodi di riciclaggio si rivelano inadeguati, in quanto mancano di efficienza e di ecocompatibilità. È qui che entra in gioco il progetto REVITALISE, finanziato dall’UE, con una soluzione innovativa. Utilizzando tecniche all’avanguardia come la frammentazione elettroidraulica e gli ultrasuoni per la purezza dei materiali, REVITALISE mira a rivoluzionare il riciclaggio delle batterie. Introduce inoltre la bonifica delle acque, estraendo il litio dai flussi di acque reflue. In collaborazione con i leader del settore Verkor, Hydro e Hydrovolt, il progetto garantisce il riciclaggio a ciclo chiuso, ottimizzando i tassi di recupero e riducendo al minimo l’impatto ambientale. L’obiettivo è un processo commercialmente valido con un impatto ambientale minimo, che incorpori l’idrometallurgia. REVITALISE stabilisce un nuovo standard per il riciclaggio delle batterie ecologico ed economico, guidandoci verso un futuro sostenibile.
Obiettivo
REVITALISE delivers a holistic solution for green, low-cost, and low environmental impact recycling of NMC (Hi-Ni), LFP and Na-Ion batteries, representing 85% of battery waste streams up to 2025. REVITALISE develops low-cost and green processes to recover a full range of battery materials, including NMC, LFP, Al, Cu, Li, graphite, fluorides, phosphates and plastics.
Overall recycling rates of 91%+ will be proven at TRL4 for waste processed from post-production scrap and end-of-life battery black mass. REVITALISE will develop innovative pre-treatment technologies based on electrohydraulic fragmentation, ultrasonication and magnetic, and electrostatic separation that will achieve very high levels of material stream purity. This will enable commercially viable recycling of low-value parts. The approach will enable direct recycling of 40% of the cathode and anode active parts, with direct characterisation of the lithiation (or sodiation) being developed that will be used as a basis of a smart-reformation approach for reclaimed active materials. The remaining 60% being suitable for hydrometallurgical recycling based on leaching with green organic acids from food waste, such as vitamin C (ascorbates), vinegar (acetate) and citric acid (citrates) and inorganic acids produced from industrial wastes.
A further innovation is the development of water remediation with Li recovery from all wastewater streams generated, through the implementation of polymeric nanocomposite membrane separation with direct Li recycling for Li in water concentrations down to 0.6mg/L.
The recycled parts will be assessed for (closed-loop) battery and other secondary applications for precursors and semi-products by industrial partners Verkor and Hydro, through reformulation and upcycling of battery materials and validation of remanufactured batteries.
An optimised process flow will be determined to achieve commercially viable recycling with maximised recovery rates and minimal environmental impact.
