Ni x Zn 1− x Fe 2 O 4 ( x =0, 0.25, 0.5, 0.75, 1) compounds were prepared by a hydrothermal method and subsequent heat treatment. The physical characteristics of the samples were investigated by field‐emission SEM, XRD, X‐ray photoelectron spectroscopy, and TEM. The electrochemical properties of Ni x Zn 1− x Fe 2 O 4 ( x =0, 0.25, 0.5, 0.75, 1) as anode materials were tested for lithium‐ion batteries. The lithium‐storage properties of the electrodes were assessed by cyclic voltammetry and galvanostatic cycling. Among the five samples, Ni 0.25 Zn 0.75 Fe 2 O 4 shows good electrochemical performance with a discharge capacity of 1488 mAh g −1 in the initial cycle and 856 mAh g −1 after 100 cycles.
