Transition metal-doped spinel cathode materials of LiM0.1Mn1.9O4 (M: Co, Ni, Cr) were prepared by solid-state reaction. The structure andmorphology of the products were investigated by X-ray photoelectron spectroscopy, X-ray diffraction, Rietveld refinement and SEM-EDX. The oxidation states of Mn, Co, Ni and Cr were found to be 3+/4+, 2+, 2+ and 3+, respectively as revealed by X-ray photoelectronspectroscopy. SEM-EDX shows uniform particles and the particle size was about 200-700 nm ranges. The diffraction peaks of theprepared solids corresponded to a single phase of cubic spinel structure with a space group Fd3m. Doping of Co, Ni and Cr causes latticeparameters to decrease. The prepared materials have ionic conductivity where LiCo0.10Mn1.90O4 has the highest capacitance.
