Ti0.9Fe1.1O3 with a solid solution structure has been synthesized and investigated as an anode material for rechargeable Li-ion batteries. Ti0.9Fe1.1O3 was prepared by a solid-state reaction of Fe, Fe2O3 and TiO2. Without other modification, the obtained Ti0.9Fe1.1O3 exhibited high discharge capacity and remarkable cycle capability compared with the commercial Fe2O3 sample. A reversible capacity of 454.9 mA h g(-1) and coulombic efficiency of 100% at 100 mA g(-1) could be achieved and kept even after 500 cycles. The prominent electrode performance could be attributed to the stable solid solution structure, in which Titanium is inactive and only support the unstable structure during reversible electrochemical processes.
