Spinel Fe2VO4 was synthesized by solid state method and its properties were characterized using XRD, SEM, TG-DSC and specific surface area measurements. The average size of the particles was 500 nm. TG-DSC test demonstrated that the Fe2VO4 was thermally stable in nitrogen atmosphere within 300 degrees C. Lithium insertion into the sample at room temperature and 55 degrees C has been investigated and the highest discharge capacity approached 250 mAh/g at an average voltage of 0.6 V vs Li+/Li. Capacity retention was unexpectedly good at 1C discharge rate at room temperature and 55 degrees C. At 5C discharge rate, the specific capacity was still 136 mAh/g. The results show that the Fe2VO4 is a promising anode material due to its high specific capacity, thermal stability and rate performances.
