A novel synthesis of nanosized spinel LiMn2O4cathode has been developed by a combination of high-gravity technology and microwave technology. Spinel lithium manganate precursor were prepared by co-precipitation method in a rotating bed with helix channels (RBHC). Calcination of the precursor in the microwave field produces uniformly sized, nanoparticles of spinel LiMn2O4as the final product. The phase structures and morphologies were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM), transform electron microscopy (TEM). The results show that nanosized spinel LiMn2O4powders with high crystallinity, uniform particle size, and the average size of about 60 nm can be synthesized by the integration of high-gravity technology and microwave technology. |
