Moreover, transition metal (TM) dissolution occurs during recycling in H2O, a phenomenon that had been previously reported for oxide-based electrode materials in other studies . In this study, during the recycling process, Mn ions (~ 0.09%) from LMO and Fe ions (~0.02%) from C-LFP were detected in the recycled Li3InCl6. Increased amounts of TMs are found in Li3InCl6 recycled from NMC and NCA, with 0.02% Ni ions detected after separation from NMC and, 0.12% Ni ions, 0.05% Co ions and 0.22% Al ions detected after separation from NCA.
