Nanostructured Morphology of Spinel LiMn₂O₄ Oxide under Microwave Heating

Abstract:

The surface morphology and structure of the cubic stoichiometric spinel LiMn₂O₄ powder prepared by microwave heating were examined using X-ray diffraction, scanning electron microscopy and transmittance electron microcopy. It is shown that the surface morphology of LiMn₂O₄ particle changed with increasing preparing temperature, while the crystal structure kept unchanged. Novel nanostructured morphologies including nanorods and nanowhiskers were formed under appropriate synthesis conditions. The growth mechanism of the nanostructured morphology of spinel LiMn₂O₄ was discussed in accordance with period bonding chains (PBCs) theory.
