ABSTRACT
Nanocrystalline spinel LiMn2O4 was synthesized by sol-gel method using aqueous solution of metal acetates (LiOAc鈥2O, Mn(CH3COO)2.4H2O) and citric acid as chelating agent. X-ray diffraction measurement showed the peaks at 2胃 values corresponding to (111), (311), (222), (400), (331) and (440) planes of cubic spinel LiMn2O4 nanoparticles with average size ~25 nm. FT IR shows all the characteristic peaks of the cubic spinel. TG/DTA measurement showed the weight loss between 100-250℃ and 300-500℃ which correspond the endothermic and exothermic processes. An exothermic peak observed at around 400℃ is due to the thermal decomposition of the ingredients to form LiMn2O4. FE-SEM measurement revealed the formation of small polycrystalline particles of almost spherical morphology with size between 20-30 nm.
