LiNixMn2-xO4 cathode materials were synthesized for Li-ion battery utilizing solution combustion approachwheremetalnitrates and urea as prepared sample. Characterization technique was investigated using XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy) and TGA (Thermo Gravimetric Analysis). It has been discovered that in the main yields generated incombustion methods, there was a fundamental crystalline LiMn2O4phase were present. Pure phase LiMn2O4was formed following additional annealing air in low temperature of 6000C. Spherical morphology of synthesized sample were obtained SEM results while TGA reveal that mass is continuous decrease with temperature and it represented by the mass loss curve. The dopant of Nickel into LiMn2O4cathode materials were comparable to those reported for characterization of the electro-chemical activities among all cathode results generated by the solution ofdirect combustion technique. As a result of the research, it was discovered that LiMn2O4 derived by combustion synthesis was high potential cathode material for LIBs (lithium ion batteries).
