The demand for lithium-ion batteries (LiB) is expected to exponentially increase in the coming years with the need to store energy to accommodate the energy transition movement. The most used raw materials for cathodic materials for LiBs are nickel, manganese, and cobalt. These metals, along with lithium, are now considered critical due to their exhausted usage and increasing economic importance. Recycling methods are established to alleviate the pressure on the demand for these materials. Hydrometallurgical methods recover the cathode active materials (CAM) in their precursor form, while lithium is recovered with low yield and purity. This study aims to integrate a lithium-recovery step in the hydrometallurgical recovery process of spent LiBs by increasing the yield and purity of lithium.
