Randomized trial investigates nickel recovery from Li-ion battery recycling, suggesting an effective purification method.

The research aims to develop a sustainable method for producing high-purity nickel from Li-ion battery recycling.
Proposed a hydrometallurgical route combining oxidative precipitation and ion-exchange purification.
Utilized Dowex™ M4195 for ion-exchange to recover nickel from residual solutions.
Analyzed the effects of sodium and potassium impurities on nickel selectivity during purification.
Achieved high purity nickel solutions exceeding 99.9%.
Demonstrated effective nickel recovery despite significant impurities (> 20 g∙L − 1).
Showed integration of techniques improves efficiency of cobalt-free cathode materials.
