Electrodeposition of metals is of wide interest with application in several fields such as electroplating, electrorefining and electrowinning (EW). Particularly, electrowinning is used in the fabrication of commercially pure copper and zinc, with approximately 20% of the world refined copper (Cu) produced by this process. One of the main advantages of EW is the high purity achieved of the final product. Electrowinning has been implemented recently as one of the final steps in the hydrometallurgical recycling process of lithium-ion batteries (LIBs) to recover some of the valuable metals present in the battery such as cobalt and nickel.
