SYNTHESIS AND CHARACTERIZATION OF ZnO-Fe2O3 ANODE MATERIAL FOR LITHIUM - ION BATTERY

Abstract

ABSTRACT ZnO nanorods are grown on seedless and seeded Si substrates, respectively using hydrothermal method. Horizontal and vertically aligned ZnO nanorods morphologies are observed on seedless and seeded Si substrates. The as grown ZnO nanorods are characterized by x-ray diffraction to know the phase formation, energy dispersive x-ray spectroscopy and photoluminescence measurement to investigate the quality of ZnO nanorods. Structural, elemental and luminescence characterization revealed that the as grown ZnO exhibit pure wurtzite phase of ZnO and of good quality. Surface morphology of as grown ZnO nanorods is characterized by scanning electron spectroscopy which confirms that the orientation of nanorods is horizontal on seedless substrate while on seeded substrate it becomes vertically aligned. Further, vertically aligned ZnO nanorods are grown on Cu foil and doped with FeSO4 for the formation of ZnO-Fe2O3 flower like hybrid structure. The potentiality of such flower like hybrid structure is explored as an anode material in Li-ion battery applications.
