Fe 2 O 3 materials with various morphologies were synthesized from iron (III) chloride (FeCl 3 .6H 2 O) by a facile hydrothermal route for Fe-air battery anodes. The crystal structure and morphology of the obtained Fe 2 O 3 powder were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The morphologies, shapes and sizes of Fe 2 O 3 particles synthesized via the hydrothermal method were controllable by the concentration of precursors. The composite electrodes were fabricated by mixing the synthesized Fe 2 O 3 powders with nanocarbon and were then subjected to electrochemical measurements. The results indicated that the shape and size of iron oxide affected the electrochemical properties of Fe 2 O 3 /carbon composite electrodes. The concentration of electrode components also significantly influenced the cyclability of Fe 2 O 3 /carbon composite electrodes
