In this work, a process has been proposed to recover cobalt and lithium elements from spent LiCoO2 batteries, then these elements were used as raw materials for the synthesis of LiNi0.6Co0.2Mn0.2O2 material. In addition, aluminum ion was selected as a dopant to modify the LiNi0.6Co0.2Mn0.2O2. The obtained materials were characterized by X-ray diffraction, scanning electron microscopy, electrochemical impedance spectroscopy and charge-discharge tests. The XRD results showed that the aluminumdoi:10.20964/2020.07.67 fatcat:aoc3jt6z6rhybmh5oo6xgnuztm
