| Abstract: | An amorphous iron oxide-carbon composite has been fabricated through an effective, inexpensive, and scalable method employing solution combustion synthesis. Amorphous iron oxide nanoparticles with diameters of about 5 nm were synthesized and uniformly embedded in a dense carbon matrix. The synthesized composite exhibits enhanced cyclability and rate capability, showing a high reversible capacity of 687 mA h g(1) after 200 discharge/charge cycles at a current rate of 0.5 A g (1), compared to the 400 mA h g (1) observed for Fe2O3 nanoparticles. This enhanced performance was retained despite more demanding conditions, delivering a high capacity of about 525 mA h g (1) and a nearly perfect coulombic efficiency even after 400 cycles at 1 A g (1). The easy production and superior electrochemical properties of this composite suggest that it is a promising material for use as an anode material in high performance lithium ion batteries. |
