Özet
© 2013 AIP Publishing LLC. LiMn 2 O 4 compound are synthesized by combustion method using glycine as a fuel at temperature (T), 800°C which was coated by a polyaniline. The goal of this procedure is to promote better electronic conductivity of the LiMn 2 O 4 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 are made in the voltage range of 3.5-4.5 V vs. Li at room temperature. Electrochemical performance of the LiMn 2 O 4 was significantly improved by the polaniline coating.
