3d transition metal oxides have been studied widely as an anode component for lithium ion batteries due to their high reversible capacities, chemical stability, and low cost. Fe is one of the more abundant metals among the various transition metals and its oxide form, Fe2O3, possesses fairly high capacity of 960 mAh g-1. Direct growth of nanomaterials on current collectors leads to efficient charge transport, and no need of polymer binder and conductive carbon. Because of the preceding facts, Fe2O3 nanoparticles have been deposited directly on stainless steel by chemical vapor deposition (CVD) method using a volatile precursor material, Fe(acac)3 (acac=acetylacetonate). As prepared materials were characterized by powder x-ray diffraction and field emission scanning electron microscope techniques. Cyclic voltammetry and galvanostatic charge-discharge experiments were carried out versus Li metal and the details will be presented.
