Depending on different preparation methods, two samples of nano α- Fe2O3, in addition to the commercial one, having different structural properties were successfully synthesized. All samples were characterized using different techniques such as X-ray diffraction (XRD), Energy dispersive X-ray spectroscopy (EDX), Infra – red spectroscopy (IR), Scanning electron microscopy (SEM), Brunauer – Emmett – Teller (BET) nitrogen adsorption – desorption isotherm and a vibrating sample magnetometer. All structural characterization parameters exhibited that the EDTA – prepared sample has the best textural structure, which support the electrochemical properties concerning the charge – discharge processes for the high rate performance of lithium –ion batteries. All results showed good anode electrochemical performance of EDTA – prepared sample at the high rates of 1C and 2C, especially the first electrochemical cycles of charge –discharge processes. A comparison with other recent previous related studies was performed to confirm the novelty and efficiency of EDTA – prepared sample for the high rate performance of lithium –ion batteries applications. |
