Hematite, with the higher theoretical capacity, as one of the most promising alternatives attract great attention in lithium-ion batteries (LIBs). However, it is suffers from severe volume expansion and shrinkage during the insertion and extraction of Li ions. Here novel 3D graphene aerogel load with hollow Fe2O3 nanotubes was synthesized with the help of polyvinyl pyrrolidone (PVP) and N-Methyl pyrrolidone (NMP) by a simple hydrothermal method. Serving as an anode material for LIBs, this composite manifested great cycle performance of high columbic efficiency (97%similar to 99%), high specific discharged capacity (1512 mAh g(-1) at 100 mA g(-1)) and high rate capability (280 mAh g(-1) at 5 A g(-1)). The superior performance of the material mainly depends on the interaction of graphene sheets and hollow Fe2O3 nanotubes. The 3D framework affords shorter diffusion distance for Li ions and enormous area to accommodate the volume expansion during the insertion/extraction of Li ions. Herein, this composite demonstrates a new way to modify the morphology of Fe2O3 and displays high efficiency and good performance as the anode of LIBs.
