▎ 摘  要

A new hybrid nanostructure composed of mildly reduced graphene oxide (mRGO) nanosheets and homogeneous loading of amorphous FeOOH with ultrafine particles (similar to 2 nm) is successfully synthesized via a facile infrared irradiation approach. Surprisingly, the as-prepared FeOOH/mRGO hybrid exhibits high reversible capacity, long-term stability, and excellent rate performance, when used as an anode material for lithium-ion batteries. A high reversible capacity of 767 mA h g(-1), with a coulombic efficiency of similar to 100%, can be achieved at a high current density of 1000 mA g(-1) even after 600 discharge/charge cycles. The superior electrochemical performances are attributed to the synergistic effects of the small particle size, amorphous structure, and conductive mRGO.
