In this work we have synthesized Li (Ni1/3Co1/3Mn1/3) O2 using sulfates metals Ni, Co and Mn and LiCl salt. The used method is easy and led to yield higher than 75%. Identification and lamellar α-type NaFeO2 of the composite synthesized were demonstrated by X-ray diffraction and FTIR spectroscopy. We demonstrated that the product is pure and its crystallinity changes according to the parameters of the annealing step. The electronic structure of the compound has been modified by doping with monovalent Cupper cation. The results are encouraging and show that the lamellar structure is not altered. We noticed an increase in infill distances that can affect the mobility of lithium cations during the insertion cycles / extraction. Indeed, the charge on the surface of the doped product is -90mV after 60 minutes and that of the undoped compound is -241mV.
