Study on Synthesis and Electrochemical Properties of Nanophase Li‐Mn‐spinel

Abstract

AbstractLi‐Mn‐spinel was synthesized using the rheological phase reaction method. First, the precursor was prepared by rheological phase reaction. Then it was decomposed to form Li‐Mn‐spinel, which was characterized by X‐ray diffraction analysis and IR spectra. The particle size of Li‐Mn‐spinel was determined by the method of the transmission electron microscopy. The synthesized materials are of nanometer size with 30—100 nm in the average diameter. The electrochemical properties of the Li‐Mn‐spinel were also studied. It proved that this method not only provided a simple practicable and effective route for the synthesis of Li‐Mn‐spinel, but also had many advantages such as lower sintering temperature, shorter sintering time, fine particles and particularly excellent electrochemical performances.
