Li-ion used batteries were used, which were discharged by immersion in NaCl solution 5% w / w, subsequently subjected to a comminution process with its respective granulometric and compositional analysis by fluorescence X-rays to identify the it cobalt content on each sieve, then a co-grinding with PVC was performed in a ball mill high energy to times of 1, 2, and 3 hours to generate a reaction between chlorine of PVC and metals present in the waste batteries to form metal chlorides. Dilution of metal chlorides was then performed in water for producing metal ions available in an aqueous medium, which were analyzed by atomic absorption spectrophotometry. Cyclic voltammetry parallel tests were conducted to determine the potential values to which the electrodeposition of metals occurs. By increasing the co-grinding time increased the amount of the obtained metal chlorides.
