This study aims to synthesize Ni-doped LiNi_xMn_2-xO₄ (x = 0, 0.02, 0.04, 0.06, 0.08, 0.1) by irradiation microwave-assisted reflux technique. The microstructure of the products was investigated by x-ray diffraction equipped with U-FIT program package. Results of the structural analysis show that Ni doping changed the size, crystallinity, and micro structure of LiNi_xMn_2-xO₄. The LiNi_xMn_2-xO₄ solids have a cubic structure with a space group of Fd-3m. Increasing the content of Ni doping does not affect the structure. The average volume of LiNi_xMn_2-xO₄ is around 555 ų to 580 ų. The crystallinity of the solids tends to increase with the increasing Ni content accompanied by the decrease in unit cell lattice parameters.
