This document is a product purity study of recycled Li-ion batteries with a concentrate on hydrometallurgical recycling processes. Firstly, a brief description of the current recycling status was presented based on the research data. Moreover, this particular work presented the influence of impurities for example Cu, Fe and Mg in recovered cathode materials overall performance. The impact from the harmful particles was described based on their particular form (metallic or ionic) and concentration. This function also reviewed hydrometallurgical recycling where possible processes depending on the particular recovered material, obtained purity and recovery methods. This purity data were acquired from both research and battery industry actors. Finally, the purity study was completed by collecting data regarding commercial battery-grade chemical substance compounds and active lithium cathode materials, including needed purity levels and allowed impurity limitations.
