In this research, Li1.25Mn0.125Ni0.125Co0.5O2 Nano powders, were synthesized using sol-gel method at different temperatures, lithium nitrate, manganese nickel cobalt nitrate as raw materials. Thermal and thermal gravimetric of TGA/DTA, characterization structure properties samples prepared by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) performed. Also, with scheme, i...
