▎ 摘　　要

Fe2O3/reduced graphene oxide (Fe2O3/rGO) composite anode materials have been successfully synthesized by a polyvinylpyrrolidone (PVP)-assisted homogeneous precipitation method. The size of Fe2O3 nanoparticles on the surface of rGO sheets was less than 35nm. Fe2O3 nanoparticles and rGO sheets formed a network structure. Electrochemical properties were evaluated in two-electrode cells vs. metallic lithium. The Fe2O3/rGO composite exhibited excellent electrochemical lithium storage performances. The first discharge/charge capacities were 1600/1053mAh g(-1) at a current density of 100mAg(-1), and the coulomb efficiencies was 65.8%. The reversible specific capacity remained 893mAh g(-1) and the capacity retention was 84.8% after 100 cycles.
