LiBinfinity - Entwicklung eines ganzheitlichen und nachhaltigen Recyclingansatzes für Lithium-Ionen-Batterien (LIB); Teilvorhaben: Entwicklung einer hydrometallurgischen Aufbereitung und flexibler Prozesssteuerung

Abstract

The project successfully demonstrated and further developed an integrated mechanicalhydrometallurgical recycling process for lithium-ion batteries. Pilot-scale campaigns validated the recovery and purification of nickel, cobalt, manganese and lithium products and provided important operational knowledge for industrial implementation. Key achievements included optimisation of solvent extraction and ion exchange circuits, development of an a manganese removal process, identification of an optimum lithium recovery route and development of a recycling approach suitable for both NMC and LFP battery materials. The project generated substantial know-how relating to process integration, impurity control, product quality and commercial scale-up.
