| Abstract: | It has become one of important topics to research and develop the cathode materials for lithium (Li) ion batteries. Current investigations focused mainly on three types of Li-rich metal oxides, LiCoO_2, LiNiO_2 and LiMn_2O_4. In this article, the synthesis methods of cathode materials for Li-ion batteries were summarized. The structures and electrochemical performances of several different cathode materials were compared. The characteristics and problems associated with the cathode materials were pointed out. In addition to provide a brief overview of the current research activities in the field of cathode materials, the progress in the field via a computational approach was also reviewed. The formation energy, phase diagram, voltage, crystal structural parameter and density of state can be calculated using VASP software package. |
