An Fe 2 O 3 /Mn 2 O 3 Nanocomposite Derived from a Metal‐Organic Framework as an Anode Material for Lithium‐ion Batteries

Abstract A facile and efficient coprecipitation was used to synthesize metal‐organic framework (MOF), which was used as the precursor to prepare Fe 2 O 3 /Mn 2 O 3 nanocomposite as anode material for lithium‐ion batteries (LIBs). Fe 2 O 3 /Mn 2 O 3 nanocomposite (synthesized by terephthalic acid) proved to show superior electrochemical performance compared to the single component, with a capacity of 1016 mA h g −1 after 240 cycles at 0.5 A g −1 , capacity retention reached 114 %. This can be attributed to the uniform nanostructure brought by the MOF precursor and the stepwise volume change process of the two metal oxides, which leads to a higher electrical conductivity with a more stable structure. Meanwhile, this novel method for the synthesis of heterogeneous structural materials could open the way for the preparation of other high‐performance hybrid materials in LIBs.
