Synthesis of LiCo0.25Ni0.75O2 via Citric-urea Combustion Route as a Cathode for Lithium-ion Batteries

The LiCo0.25Ni0.75O2 compound was prepared by a citric-urea combustion rout in this study. the study presented a comprehensive analysis of the decomposition process and formation of metal oxides in LiCo0.25Ni0.75O2 sample using Thermogravimetric Analysis (TGA), Crystalline structure and surface morphology of the prepared powder are investigated by (XRD) and (FESEM). The results of the XRD patterns for LiCo0.25Ni0.75O2 sample show high intensity peaks that indicated a good crystallinity with the Calcination Temperature, while the morphology results show indicates that sample was in the nanostructure dimensions. Electrochemical measurements showed The capacity of the charging and discharging were of 177.6 mAhg-1 and 166.9 mAhg-1 delivered by the LiCo0.25Ni0.75O2 cathode. Likewise, a columbic efficiency of 93.9% was obtained for the cathode.
