摘要：

LiMn2O4 compound arc synthesized by combustion method using glycine as a fuel at temperature (T), 800 degrees C which was coated by a polyaniline. The goal of this procedure is to promote better electronic conductivity of the LiMn2O4 particles in order to improve their electrochemical performance for their application as cathodes in secondary lithium ion batteries. The structures of prepared products have been investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). To investigate the effect of polyaniline coating galvanostatic charge discharge cycling (148 mA g(-1)) studies arc made in the voltage range of 3.5-4.5 V vs. Li at room temperature. Electrochemical performance of the LiMn2O4 was significantly improved by the polaniline coating.
