抄録

Novel Fe3C carbon composite was proposed as new low cost and low environmental impact anode for Li-ion battery. Although the delithiated capacity of Fe3C without AB were 100 mAh g−1 in the first cycle at a rate of 7 mA g−1, that of Fe3C with AB was improved to 230 mAh g−1 at a rate of 50 mA g−1. Moreover, nanoparticle-Fe3C carbon composite including a relatively high-purity Fe3C could be obtained from α-Fe2O3 and ion-exchange resin. The best initial delithiated capacity more than 320 mAh g−1 at a rate of 50 mA g−1 and improved anode performance were obtained in the Fe3C-carbon composite sintered at 650°C.
