Abstract
Depending on different preparation methods, two samples of nano alpha- 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), Fourier transform infrared spectroscopy (FT-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 1 C and 2 C, 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.
