“…Two peaks located at 516.1 and 517.5 eV are assigned to V 4+ 2 p 3/2 and V 5+ 2 p 3/2 . Similarly, another two peaks at 523.6 and 524.9 eV correspond to the V 4+ 2 p 1/2 and V 5+ 2 p 1/2 , respectively . The existence of V 4+ confirms the partial reduction of the V 2 O 5 due to the preintercalated sodium ions …”

Rechargeable aqueous Zn‐ion batteries (ZIBs) show attractive potential in energy storage devices on account of high safety and eco‐friendliness. Yet the lack of suitable cathode materials prevented the practical application of ZIBs. In our work, a Na0.56V2O5 (NVO) nanobelt cathode material has been fabricated via a hydrothermal reaction. The prepared NVO samples reveal an expanded layer spacing, assisted by the chemical intercalation of Na+ into the V2O5. Particularly, a mild hybrid cationic electrolyte (0.5HCE, containing 3 M ZnSO4 and 0.5 M Na2SO4) was employed to replace the traditional ZnSO4 electrolyte (ZE) in the Zn//NVO system. Owing to the enlarged interlayer spacing and the protective effect of 0.5HCE, the NVO cathode delivers a preferable capacity and good cyclic stability. More specifically, the NVO cathode in 0.5HCE displays a high initial discharge capacity of 317 mAh g−1 at 0.1 A g−1, and exhibits a good stability after 1000 cycles at the current density of 1 A g−1. Besides, the Zn//NVO battery also presents a favorable rate capability and a high reversibility. This study could provide new directions for the development of low‐cost zinc ion batteries.

“…[ 21,22,27,76 ] For example, metal‐ion intercalation, including Li + , Na + , K + , Mn 2+ , and Zn 2+ , is explored to improve the performance of V 2 O 5 cathode materials. [ 77–81 ] It is worth to note that a recent report by Liu et al. revealed that the chemical insertion of Mn(II) cations in hydrated vanadates can act as structural pillars, which expand the interplanar spacing from 11.9 to 12.9 Å, linking the adjacent layers and partially reducing the pentavalent vanadium cations to tetravalent (see Figure a).…”

Zinc-ion batteries (ZIBs) have attracted intensive attention due to the low cost, high safety, and abundant resources. However, up to date, challenges still exist in searching for cathode materials with high working potential, excellent electrochemical activity, and good structural stability. To address these challenges, microstructure engineering has been widely investigated to modulate the physical properties of cathode materials, and thus boosts the electrochemical performances of ZIBs. Here, the recent research efforts on the microstructural engineering of various ZIB cathode materials are mainly focused upon, including composition and crystal structure selection, crystal defect engineering, interlayer engineering, and morphology design. The dependency of cathode performance on aqueous electrolyte for ZIB is further discussed. Finally, future perspectives and challenges on microstructure engineering of cathode materials for ZIBs are provided. It is aimed to provide a deep understanding of the microstructure engineering effect on Zn 2+ storage performance.
