Fe2O3 and ZnO.Fe3O4 hybrids has been synthesised by molten salt method and tested as anode material for Li-ion batteries. The crystal structure and phase purity was evaluated by X-ray diffraction and the morphology of the final powders was examined by the Scanning electron microscopy. The Li-cycling properties of Fe2O3 and ZnO-Fe3O4 were studied by cyclic voltammery (58 μV s-1) and galvanostatic discharge-charge cycling in the voltage range, 0.005- 3 V at a current of 60 mA g-1. The Fe2O 3 samples prepared at 280 C and 900 C showed stable reversible capacities of 600 and 620 mAhg-1 at the end of 50 cycles respectively. On the other hand, ZnO.Fe3O4 hybrids showed improved and stable capacity of 820 mAh g-1 at the end of the 50th cycle. © 2013 Elsevier Ltd. Source
