▎ 摘　　要

FeOOH nanorods (NRs) wrapped by reduced graphene oxide (rGO) were fabricated using a facile solvothermal method. When used as anode materials for lithium-ion batteries (LIBs), the FeOOH NRs/rGO composites show a higher capacity (490mAh g (-1) after 100 cycles at a current density of 100mA g (-1) THORN and better rate capability than pure FeOOH NRs. The enhanced electrochemical performance can be ascribed to the hybrid structure of FeOOH and rGO. On one hand, the introduction of rGO can improve electronic conductivity and reduce charge-transfer resistance for electrode materials. On the other hand, the distinctive structure (FeOOH NRs surrounded by degrees exible rGO) can e (R) ectively bu (R) er large volume change during the Lithorn insertion/extraction process. Our work provides a feasible strategy to obtain high-performance LIBs.
