Although cobalt has been commercialized as cathode material in layered lithium ion batteries, numerous attempt had been made to find an appropriate alternative candidate due to the high price, toxicity and instability of cobalt. Presently, with maintaining the existing battery's characteristics, cobalt free, eco-friendly layered cathode material developments are continued. Therefore, in this research, the MgO was coated in many conditions in order to increase the electrochemical characteristics of the active cathode material. In addition, the composition of the layered cathode active material was confirmed through XRD. Finally the electrochemical analysis was confirmed through the cyclic voltammetry and impedence. |
