Core‐shell architectures with hollow micro‐structures have exhibited many potential applications in electrochemical energy storage fields. In this study, hierarchical Fe 2 O 3 @NiCo 2 O 4 core‐shell tubular arrays have been synthesized by a multistep chemical bath deposition method. The obtained samples have been fully characterized using powder X‐ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis. The results show that NiCo 2 O 4 nanosheets have been uniformly coated on the Fe 2 O 3 tubular array obtained by ZnO array template. When tested as an anode for lithium ion battery, the Fe 2 O 3 @NiCo 2 O 4 tubular arrays have been found to exhibit an improved specific capacity of 587 mAh g −1 at a current density of 1000 mA g −1 , good rate capability and cycling stability.
