The recycling of used Li-ion batteries is important as the consumption of batteries is increasing every year. However, the recycling of electrode materials is tedious and energy intensive with current methods, and part of the material is lost in the process. In this study, an alternative recycling method is presented to minimize the number of steps needed in the positive electrode recovery process. The electrochemical performance of aged and re-lithiated Mg−Ti-doped LiCoO₂ and stoichiometric LiCoO₂ was investigated and compared. The results showed that after re-lithiation the structure of original LiCoO₂ was restored, the capacity of an aged LiCoO₂ reverted close to the capacity of a fresh LiCoO₂, and the material could thus be recovered. The re-lithiated Mg−Ti-doped LiCoO₂ provided rate capability properties only slightly declined from the rate capability of a fresh material and showed promising cyclability in half-cells.
