Metal–organic frameworks (MOFs) may be promising multifunctional materials attributing to their large internal surface areas and high porosities that can favor charge transport. In this article, MIL-53(Fe) has been investigated as an anode material for Li-ion batteries. It showed decent performance on account of the redox reaction (Fe 3+  ↔ Fe 0 ). However, the carboxylate groups of terephthalate acid ligands did not show electrochemical activity due to the poor electrical conductivity of MIL-53(Fe) and the formation of thick solid electrolyte interphase layer. In this case, reduced graphene oxide (RGO) was then composited to resolve the problem, which named as MIL-53(Fe)@RGO. The composite exhibited better electrochemical performance than the sole MIL-53(Fe). Specifically, a reversible discharge specific capacity of 550 mA h g −1 could be still achieved at 100 mA g −1 after 100 cycles within the voltage range of 0.01–3.0 V, an reversible discharge capacity of about 300 mA h g −1 was obtained even at 2 A g −1 . These values are much higher than those of currently used graphitic materials. RGO makes it even more possibility for MOFs to be adopted as electrode materials for Li-ion batteries.
