In recent years, with the increasing use of lithium-ion batteries (LIBs), recycling their valuable metals has become very important not only from an environmental but also from an economic perspective. In this study, an effective and environmentally-friendly approach was proposed for leaching cobalt and lithium from LIBs by using glycine. Accordingly, after the initial preparation of lithium-ion batteries, in the first stage, the dissolution of the metals manganese, cobalt, nickel, and lithium in a glycine solution (1 M glycine concentration, 60 min, and 60 °C) was carried out. After investigating several effective parameters, different metals were precipitated from the solution in several stages. Using oxalic acid at pH = 2, nickel oxalate (NiC<sub>2</sub>O<sub>4</sub>) was precipitated from a glycine solution. Then, by increasing the pH to the alkaline range (about 8) with soda and ammonia, manganese and cobalt hydroxides were precipitated. Finally, by adding sodium carbonate, lithium carbonate was obtained. At each stage, the composition of the precipitate and the solution contents were determined by ICP, XRD, and FESEM analyses.
