Li $_{1.2}$ Ni $_{0.13}$ Mn $_{0.54}$ Co $_{0.13}$ O $_{2}$ is known as one of the cathode electrode material for Li ion batteries and its structure during charge and discharge process was investigated using electrochemical method and X-ray diffraction. It was found that in the charge process the structure changes in the order of Li $_{2}$ MnO $_{3}$ , LiNi $_{0.33}$ Mn $_{0.33}$ Co $_{0.33}$ O $_{2}$ , and Li $_{2}$ MnO $_{3}$ . On the other hand, in the discharge process, the structure changes in the order of Li $_{2}$ MnO $_{3}$ and LiNi $_{0.33}$ Mn $_{0.33}$ Co $_{0.33}$ O $_{2}$ .
