Li-ion battery (LIB) cathode materials are regenerated from spent LIBs. Precursor of Li [Ni x Mn y Co z]O 2 is prepared from actual industrial scale LIB leachate. Nonmetal impurity elements such as F are detected as well as metal elements. Yield of precipitation is introduced to analyze the precipitation behavior.
To control the level of inorganic impurities in battery components, raw material suppliers and manufactures analyze the level of trace metals in the chemicals, typically using a sensitive, multi-element technique such as ICP-MS.
Therefore, it is vital that manufacturers can identify the presence of impurities in lithium battery materials to ensure that there is no compromise in final battery performance. ICP-OES is currently the most commonly employed method for analyzing Li salt compounds for purity.

Impurities in a lithium battery can reduce its coulombic efficiency by blocking Li ions, affecting its ability to charge and discharge effectively. Additionally, impurities can encourage the formation of dendrites on the anode, which can pierce the battery's separator and lead to a short circuit.

In this study, we unveil that a 1% Mg impurity in the lithium precursor proves beneficial for both the lithium production process and the electrochemical performance of resulting cathodes. This is attributed to the increased nucleation seeds and unexpected site-selective doping effects.
Notably, the highest cost of lithium production comes from the impurity elimination process to satisfy the battery-grade purity of over 99.5%. Consequently, re-evaluating the impact of purity becomes imperative for affordable lithium-ion batteries.
