Summary: Zinc-ion batteries (ZIBs) are gaining attention as a promising alternative to lithium-ion batteries (LIBs) due to their abundance of zinc source, satisfactory safety levels, low cost, and eco-friendliness. However, the volume expansion of vanadium pentoxide (V2O5) during the aging process of ZIBs limits its capacity utilization. In this study, nanosized split V2O5 with H2O-intercalated interfaces (NSVOHI) is prepared as a ZIB cathode material without an aging process, resulting in stable capacity behavior, excellent energy storage performance, and reversibility.

Summary: In this study, a hexagonal Cs0.3V2O5 cathode material is successfully fabricated and investigated in zinc-ion batteries. Compared with traditional vanadium oxides, the introduction of Cs changes the atomic arrangements, stabilizes the structure, and facilitates the diffusion of Zn2+. This leads to a high specific capacity of 543.8 mA h g(-1) at 0.1 A g(-1) and excellent cycle life over 1000 cycles with 87.8% capacity retention at 2 A g(-1). Additionally, the morphological evolution and energy storage mechanisms are revealed. This work introduces a phase engineering strategy for the fabrication of hexagonal vanadium oxide cathodes and elucidates their application in zinc-ion batteries.

Summary: Aqueous zinc-ion batteries have great potential in energy storage devices due to their abundant zinc resources and intrinsic safety. However, developing suitable cathode materials that match with the anodes remains a significant challenge. In this study, we designed carbon-coated V2O5 microspheres through a chitosan-assisted route. The amorphous carbon layer effectively enhances the electrical conductivity of the active materials, thereby improving the electrochemical performance. The assembled Zn/V2O5@0.25C batteries achieved a specific capacity of 532.4 mAh g(-1) at 0.2 A g(-1) with an energy density of 354.9 Wh kg(-1). They exhibit long-term cycling stability with a retention rate of 86% after 3000 cycles at 5 A g(-1).

Summary: Antimony-doped tin oxide (ATO) was prepared by co-precipitation method and used for surface modification of spherical zinc oxide to obtain ZnO@ATO composites with excellent properties. As an anode material for zinc-nickel batteries, ZnO@ATO exhibits superior performance in terms of cycle life and stability, attributed to the optimization effect of ATO on the ZnO electrode. ATO enhances conductivity, specific surface area, electron transfer, and current density homogeneity, effectively suppressing polarization effect in electrode reaction. Electrochemical test results show that ZnO@ATO maintains a discharge specific capacity of 561.8 mAh•g(-1) after 1950 cycles, which is 96% of the initial discharge specific capacity (583.6 mAh•g(-1)), demonstrating excellent cycle life and capacity retention.
