•Pure-phased Li2FeSiO4/C is prepared by the sol–gel method with Fe2O3 nanoparticle.•The particle size of Li2FeSiO4 is close to Fe2O3 nanoparticle.•It owns stable cycle performance at 0.1C to 5C rate.•It has good rate performance.
Li2FeSiO4/C has been prepared by the ultrasonic-assisted sol–gel method with about 50 nm Fe2O3 particle as Fe source. The structures, morphologies, and carbon content of the product are characterized. Li2FeSiO4/C owns pure phase and the particle size of Li2FeSiO4 is close to Fe2O3 nanoparticle. As the cathode material of Li-ion battery, the product shows stable cycle performance at the wide range of rate and good rate performance. The discharge capacities of the 100th cycle are 140 mAh g−1, 125 mAh g−1, 120 mAh g−1, 110 mAh g−1, and 90 mAh g−1 at 0.1C, 0.5C, 1C, 2C, and 5C rate, respectively.
