In recent years, binary transition metal oxides have been more and more widely applied as anode materials for lithium‐ion batteries (LIBs) because they can enhance the electrochemical performance beyond that of single transition metal oxides. In this work, we prepare ZnFe 2 O 4 ‐MWCNTs composite by synthesizing ZnFe 2 O 4 via a hydrothermal method with further heat‐treatment and a final mixing of ZnFe 2 O 4 with multi‐walled carbon nanotubes (MWCNTs). The ZnFe 2 O 4 ‐MWCNTs composite as an anode material for LIBs demonstrates high specific capacity (908 mAh g −1 at a current density of 100 mA g −1 after 100 cycles) and good rate performance (566 mAh g −1 even at current density of 750 mA g −1 after 70 cycles). This superior electrochemical performance shows the promise of ZnFe 2 O 4 ‐MWCNTs composite as an alternative anode material for LIBs.
