Abstract
-
n 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 ZnF e

-MWCNTs composite by synthe-
sizing ZnFe

via a hydrothermal method with further heat-
treatment and a final mixing of ZnFe
2
O

with multi-walled
carbon nanotubes (MWCNTs). The ZnFe

-MWCNTs composite
as an anode material for LIBs demonstrates high specific
capacity (908 mAh g

at a current density of 100 mA g

after
100 cycles) and good rate performance (566 mAh g

even at
current density of 750 mA g
1
after 70 cycles). This superior
electrochemical performance shows the promise of ZnFe
