Recycling and reuse of lithium (Li) has been a major topic of concern with the increasing amount of rechargeable batteries for electric vehicles (EVs) and other technologies relying on lithium. Ion exchange was used in this report Ion-exchange technique is a potential solution to concentrate and recover Li from the process water after a battery recycling operation. In this report, four different resins, Amberlite IRC 120, Lewatit TP Monoplus 208,Lewatit TP Monoplus 260 and Puromet MTS 9500 were used to identify the selectivity for Li vs Al/Cu/Ni/P/Ca/Mg/K /Na/Co. 15 mM standard solutions were used for determination of selectivity of Li against each competing ions. Two surrogate solutions of process water from battery recycling operation with varying concentrations of ions were then tested.
