Preparation of Nanosized Spinel Lithium Manganate by an Integrated Technique of High-Gravity Technology and Microwave Technology

Abstract:

A novel synthesis of nanosized spinel LiMn₂O₄ cathode 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 LiMn₂O₄ as 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 LiMn₂O₄ powders 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.
