Fe1.5Ti0.5O3 nanoparticles as an anode material for lithium-ion batteries

Iron titanium oxide (Fe1.5Ti0.5O3) nanoparticles with the diameter of about 150 nm were prepared by hydrothermal process and further heat treatment at 300 degrees C for 2 h. The morphology, structure and electrochemical performance of Fe1.5Ti0.5O3 nanoparticles as anode material for lithium-ion batteries were investigated by scanning electron microscopy, X-ray diffraction and a variety of electrochemical testing techniques. It was found that, compared with TiO2 and Fe2O3, the iron titanium oxide electrode exhibited higher specific capacity of 734.9 mAh g(-1) after 50 cycles at the current density of 50 mA g(-1), good cycle stability and high-rate performance, suggesting that the Fe1.5Ti0.5O3 nanoparticle synthesized by this method is a promising anode material for lithium-ion batteries.
